Detta examensarbete är en beredning för Fortum Distribution AB. Avsikten är att ansluta två stycken nybyggda vindkraftverk till det befintliga elnätet. Samtidigt genomförs en förstärkning av distributionsnätet genom kablifiering (kabelförläggning i mark) samt rasering av det befintliga luftnätet. Platsen för projektet är belägen strax norr om Mariestad. Projektet är uppdelat i tre deletapper. Deletapp ett (huvudprojektet) heter Vindkraft Lyrestad – Värlsen. De nybyggda vindkraftverken i huvudprojektet kommer att anslutas till ställverket i Lyrestad. Gällande deletapp 2/3, högspänningen 10 kV, kommer matningen till distributionsnätet från en befintlig stolpstation L9083-40054 som står i Ödegården. Stolpstationen som står i Ödegården kommer även att mata fem nya markstationer längs sträckningen. Lågspänningen 0,4 kV kommer idag från stolpstationer som kommer att raseras och ersättas med markstationer. Beredning är utförd av Jonas Gustafsson på konsult företaget PSN Kraftkonsult i Vedum. Hela projektet omfattar ett 15-tal berörda lågspänningskunder som kommer få sin servis nedgrävd samt en schaktsträcka för högspänningskabel på ca 8 km. Detta är fördelat på sträckningen mellan Lyrestad – Värslen via fem stycken nya markstationer.

D.Ing. / The propagation of fast disturbances along power transmission structures depends on the parameters of the excitation for the disturbance, the characteristics of the power transmission structure, and eventually on the characteristics of the electrical load connected to the structure. This thesis will therefore target the determination of the parameters of transmission structures in Chapter 2, applicable transmission-line theory in Chapter 3, modelling the load in Chapter 4, and apply this knowledge to the specific problem of over-voltages on the terminals of machines fed via cables from inverters in Chapter 5. The rest of this chapter is devoted to explaining the introductory aspects of this application problem.

M.Ing. / Electrical quality of supply affects every consumer, from the homeowner to large industry and mining. Customer awareness of poor power quality is increasing due to the more sensitive nature of modern equipment. The positioning of a new plant is therefore very important and cannot only be determined by the availability of resources in the area. To determine the quality of the electricity in a certain network, years of historical data is required. To get enough information regarding a distributions network performance would require voltage dip measurements at a few places in the network for at least three years. For this reason a new method are used in this study. By using the existing information in a network, like: • The amount of lightning strikes per year • The amount of electrocuted birds • The type of protection used • The amount of vandalism incidents on a line per year • The tower footing resistance • The fault level in the network The fuzzy logic principle can be used to determine how susceptible a network is to voltage dips, by determining the favourable and unfavourable conditions for a number of membership functions. Conventional set theory (Boolean) states that an element is either a member of a set or not. Fuzzy logic is an extension of conventional set theory enabling an element to belong to a set degree. This study will look at all the important factors influencing voltage dips, and to use these factors in a fuzzy logic program to determine the voltage dip risk factor for new customers setting up plant in a specific network. The voltage dip risk factor will then determine if it is cost effective for a customer to take on the additional cost in dip proofing his plant.
