A ?gua tem import?ncia fundamental na ind?stria farmac?utica, participa dos processos de limpeza de materiais e superf?cies, al?m de ser utilizada como ve?culo em formula??es, exigindo uma s?rie de especifica??es f?sico-qu?mica e microbiol?gicas. O processo de purifica??o da ?gua deve passar rotineiramente por um controle de qualidade r?gido e deve possuir um processo industrial conciso, automatizado e eficiente, de acordo com a legisla??o vigente. A utiliza??o de redes de automa??o e sistemas supervis?rios est? longe de ser novidade em qualquer tipo de ind?stria, por?m, neste caso, a planta industrial objeto de estudo n?o utilizava estas ferramentas. Para atingir o objetivo proposto fez-se a implementa??o de uma rede de comunica??o industrial entre os equipamentos da planta, atrav?s de uma rede padr?o MODBUS, uma rede instrumental com sinal de corrente el?trica e uma rede padr?o Ethernet. Concentrou-se os dados de leituras das vari?veis dos equipamentos no CLP mestre, este por sua vez ligado a um sistema SCADA. Este SCADA fornece ao operador uma vis?o panor?mica do processo, informando-o em tempo real o comportamento das vari?veis provenientes das etapas do processo, facilitando qualquer interven??o ou mudan?a no sistema. Os dados mais importantes s?o armazenados diariamente em arquivos na esta??o do SCADA, ficando dispon?veis para futuras auditorias ou durante a valida??o anual da planta, comprovando a efic?cia e seguran?a de todo o sistema. / This document propose the adequace of a water treatment station, through the development and implementation of an automation and supervision system for purified water production used in the manufacture of medicines. Water is of fundamental importance in the pharmaceutical industry, it participates in the cleaning processes of materials and surfaces, as well as being used as a carrier in formulations, requiring a series of physicochemical and microbiological specifications. The process of water purification must routinely pass through a strict quality control and must have a concise, automated and efficient industrial process, according to the current legislation. The use of automation networks and supervisory systems is far from novelty in any type of industry, however, in this case, the industrial plant under study did not use these tools. In order to reach the proposed objective, an industrial communication network was implemented between the plant equipments, through a MODBUS default network, an electric current signal instrument network and an Ethernet network. The variables input data of equipaments were concentrated in the master PLC, which was connected to a SCADA system. This SCADA provides the operator with a panoramic view of the process, informing it in real time the behavior of the variables from the process steps, facilitating any intervention or change in the system. The most important data is stored daily in files at the SCADA station, becoming available for future audits or during the annual validation of the station, proving the effectiveness and security of the entire system.

Reliability of wind turbine components and maintenance optimisation are among the critical aspects of wind power development closely related to profitability and future development. The main reason for research in these areas is lowering the cost of energy production for wind power, specifically important in offshore environment. Continuous monitoring of specific wind turbine components can be valuable for wind farm operators and, subsequently, wind farm owners.  Also, health assessment of critical components can be useful in estimating the possibilities for life extension of wind turbines. Expensive Condition Monitoring Systems (CMSs) are not always available, particularly in older wind farms, and additionally installing CMSs on wind turbines is not always economically feasible. However, most of modern wind turbines are equipped with the Supervisory Control And Data Acquisition (SCADA) system which is recording 10-minute average values of parameters that depict operation of the turbine. That being said, SCADA data contains a vast amount of information that can be used for analysis of wind turbine components health. Therefore, this project will present an application of previously published methodology for SCADA data condition monitoring on real wind farm data. The goal of this project is to investigate on the possibilities of the SCADA monitoring methodology and what can be the added value of the application for wind farm operators, owners and other stakeholders. The methodology for condition monitoring through SCADA data was applied on real data gathered from two wind farms in Germany and one in the Netherlands. During the project the methodology had to be modified in order to ensure the best possible industrial application. Results of the project showed that the SCADA data condition monitoring approach is not capable of predicting failures. However, the technique has been proven successful for detecting the changes of trends in dependencies of working parameters, specifically monitoring parameters related to the turbine generators. Continuously monitoring the dependencies of working parameters can be used as an additional source of information for maintenance scheduling and assessment of components health. The approach presented in this paper can be valuable to asset managers and wind farm owners.

Over the last few decades, wind power has shown a continuous and significant developmentin the energy market globally. Having reached a certain level in both technologyand in dimensions, the role of optimizing wind turbines as well as wind farms hasbecome an additional aspect to future development and research. Since turbine wakescan cause significant power deficits within a farm, research in this area has the potentialfor large improvements in wind farm design. A wake is described as the downstream flow behind the rotor of an operating windturbine. The two main characteristics of wakes are a velocity (momentum) deficit and anincreased turbulence level. The velocity deficit behind the upwind turbine results in apower loss of the downstream turbines, whereas the higher turbulence causes additionalloads on the downstream turbines’ structures resulting in fatigue problems. The study of wakes is a complex topic, they are influenced by an interconnection of anumber of parameters like ambient wind speed and turbulence, atmospheric stabilityconditions (stable, unstable, and neutral), the turbines’ operational characteristics, andthe terrain properties. In order to assess the power deficits affected by wake interaction between turbines,an analysis can be realized by processing SCADA data of turbines in a wind farm. The collected data is treated by a comprehensive filtration process, excluding events of icing, curtailment, faults, etc. and by grouping into different atmospheric conditions, windspeed intervals and wind speed sectors. Finally, power deficit values, as a function ofwind direction, are calculated and quantified, and thereafter analyzed to assess the wakebehavior at different conditions for different cases.In this thesis, the wake-induced power deficit has been investigated in a specificstudy case for three pairs of two neighboring turbines in a forested moderately complexterrain using SCADA data. The production losses amounted between the range of 32% to 67% for the specific site with turbine spacing around 4D. The obtained results werepartially unsatisfactory, caused by the reasons of inaccurate wind direction values due toyaw misalignment issues and challenging separation into different stability conditions. Moreover, the power deficits showed a clear reduction of losses with increasing windspeed. A conclusion regarding the differences between stable and near neutral conditionscould not be determined from the data.

Även fast de flesta kanske skulle tänka på en industri när de hör talas om ett övervakande system, är det något som ökar inom fastighetsautomation idag. I och med att dagens byggnader blir mer intelligenta ökar behovet av att ha full koll på alla delar i ett fastighetssystem. Genom att implementera ett överordnat system, också kallat för SCADA system, kan en fastighet övervakas från ett och samma ställe vilket ger användaren full koll på vad som händer i en byggnad. Målet med detta arbete är att beskriva kommunikationen mellan ett överordnat och ett underliggande system samt att realisera ett SCADA system. Först beskrivs hur ett överordnat system fungerar och det följs upp med en utredning kring kommunikationsstandarden som ligger till grund för hur ett fungerande SCADA sedan kan implementeras. Med tanke på dagens användning av internet väcks genast frågan kring hur säkert ett liknande system kan implementeras i ett hus utan att det kan hackas av utomstående, vilket besvaras utifrån teorin. Slutsatsen är den att ett överordnat system har väldigt stor potential med tanke på att nästintill varje hushåll idag har internet och en dator eller mobil enhet. Kan man bortse från säkerhetsriskerna och hur stor kostnaden kan tänkas bli för att köpa sig ett liknande system är detta framtiden i våra hushåll. / Even though you probably first of all would think about industries when you hear about a monitoring system its something that is increasing in building automation today. As today's buildings become more intelligent, the need to gain full control of all parts of the system increases. By implementing a superiorvisory system, also known as a SCADA system, a property can be monitored from one location, giving the user a full overview of what's happening in the building. The aim of this work is to describe the communication between a supervisory and underlying system and to put togheter a small SCADA system. First of all is a description of how a superior system works and is followed up with an investigation about the chosen communication standard. A standard that underlies how a functional SCADA then can be implemented. Keep in mind of today's use of the Internet, it is at instance a question of how safe a similar system can be implemented in a house without being worried about third parties hacking your system. The conclusion is that this sort of system have a big potential when almost everyone has a computer and Internet at home. If you can neglect the security risks and how much the cost may be to buy a similar system is that this is the future in our houses.

In the theoretical part, the industrial protocols are described, there are defined vectors of attacks and is described security of each protocol. The practical part is focused on the description and simulation of security incidents. Based on the data gathered from the simulations, there are identified threats by the introduced detection methods. These methods are using for detecting the security incident an abnormality in the network traffic by created formulas or machine learning. Designed methods are implemented to IDS (Intrusion Detection System) of the system Zeek. With the designed methods, it is possible to detect selected security incidents in the destination workstation.

This diploma thesis explains the principle of SCADA systems and describes the DLMS/COSEM protocol. In the next part, it shortly describes the Modbus protocol and details the pros and cons of the Modbus protocol in comparison with the DLMS/COSEM protocol. In the next part, an open-source automated scanner was created. This scanner detects devices in a laboratory network. As the next step, the automated scanner finds out open ports and active services, which run on these devices, and tries to attack HTTP, SSH, and Telnet services. Next, the program checks, whether the found device is a smart-meter device and if it is compatible with DLMS/COSEM protocol. If yes, it checks, if the service is vulnerable to DOS attack and breaker disconnection. Scanner’s findings are presented in a newly created web application. NMAP, Masscan, and Metasploit open-source programs are used in the automated scanner. The whole automated scanner is optimized for the HW device Raspberry Pi with the operating system Raspbian Buster Lite installed. This work also describes the testing of the scanner on the laboratory environment and the results are evaluated afterwards.

This thesis is focused on IEC 61850 communication protocols SMV, GOOSE and MMS and their implementation in SCADA systems. There is a simulator, run on Raspberry Pi, that generates data according to IEC 61850 and transmits the data using protocols in question. The simulation consist of various virtual devices e.g. surge protection, undervoltage protection, circuit breaker, disconnector, HMI. The MMS protocol is used for station control. Simulation can be user-defined from textual configuration file.
