Facing a rapidly-changing power industry, the electrical engineering department at Cal Poly San Luis Obispo proposed Advanced Power Systems Initiatives to better prepare its students for entering the power industry. These initiatives call for the creation of a new laboratory curriculum that uses microprocessor-based relays to reinforce the fundamental concepts of power system protection. This paper summarizes a laboratory system fit for this task and presents a set of proposed laboratory experiments to establish a new laboratory course at Cal Poly. The experiments expose students to the capabilities of industry-standard microprocessor-based relays through hands-on procedures that demonstrate common power system protection schemes. Relays studied in this project support transformer, transmission line, and induction motor protection.

Microgrids—miniature versions of the electrical grid are becoming increasingly more popular as advancements in technologies, renewable energy mandates, and decreased costs drive communities to adopt them. The modern microgrid has capabilities of generating, distributing, and regulating the flow of electricity, capable of operating in both grid-connected and islanded (disconnected) conditions. This paper utilizes ETAP software in the analysis, simulation, and development of the Cal Poly microgrid. Additionally, an ETAP power system protection tutorial is created to aid students entering the power industry. Microprocessor-based relays are heavily utilized in both the ETAP model and hardware implementation of the system. Case studies in this project investigate electric power system load flow, short circuit, protection coordination, and transient stability analysis of the Cal Poly microgrid.

Today's globalized world is much more vulnerable than we are often willing to admit. We live in a society which is considerably dependent on a stable supply of electricity. Potential large power outage also called blackout may be a very dangerous situation for our community. Usually we don't realize all consequences there can be for our everyday life, people's health, the security and the economy of the country. Despite the efforts of the responsible authorities, the complications for the population can be very serious. The effects of such unfortunate event can be reduced in a variety of ways. An option is to support an informed society that can take care of itself in times of crisis. This text is focused on the current approach to raising and maintaining awareness of the people for masive power outage not only in the Czech Republic. The aim of the thesis is to compare the information environment of the Czech Republic with the situation in neighboring Germany. It is important to keep on mind that many important systems serving under normal conditions to inform the population will not work when such an event occurs. It can be necessary to proceed with alternative solutions and communication channels. In the education context, it's realisic to inform the majority of the population only about the most important measures and appropriate patterns of blackout behavior. With the restoration of energy supplies, the task of informing the population doesn't end. By selecting key information, this work could contribute to the society.

The graphical user interface provides not only a good computational performance, but also an user-friendly teaching software. With the use of this interface the user can edit the input and output data files of the selected systems and can visualize and analyze the results of the program directly in the computer screen. Directly from the system one-line diagrams, the graphical user interface allows the user: to change the parameters of the system (bus and lines system data); to remove the transmission line clicking directly on it; to visualize the bus voltage profile, and the active and reactive power flows. All these characteristics make the developed program recommended for educational purposes.

Contributing to the work of philosophers of education who have been examining issues of economy and emancipation, this dissertation employs a set of critical lenses drawn from Foucault’s investigation of governmentality to trace correspondences between economic liberalism and public schooling in Upper Canada/Canada West, the historical antecedent of present day Ontario. The analysis adheres to Foucault’s advice that philosophical critique involves a question asked of the present but answered in history. Thus through a Foucauldian genealogy it is argued that a series of transformations in the deployment of governmental power occurred in Upper Canada/Canada West that entailed the entry of an economic rationality into deliberations over the creation of a school system. To support this argument evidence is presented that demonstrates how race, biopolitics, and the burgeoning science of political economy combined in the first half of the nineteenth century to form the conditions of possibility for governmental control of schooling. In particular, it is illustrated how these conditions favoured a pedagogy based in Locke’s epistemology, and were legitimized by the providential status accorded political economy. This pedagogy, which was promoted as mild and so conducive to student engagement, and the authority of political economy are revealed as integral to the methods of instruction and curriculum of the province’s common schools, and indicative of the legacy of economic liberalism that persists, albeit transformed, in Ontario education to this day. The result of this critical analysis is a redescription or, in Foucault’s terminology, a “countermemory” of Ontario educational history that challenges the presumed naturalism of the ideals characteristic of economic liberalism, such as autonomy, accountability, entrepreneurialism, and consumer choice. The dissertation contends that these ideals are active in local educational regimes long legitimized by economy, and dangerously aimed at fostering political consent by manipulating subjects into locations of restricted agency. Providing insight into the historical role played by liberal governmentality and economy in the local context contributes to the study of Foucault and the philosophy of education, and also suggests a change in approach to questions regarding the corporatization or marketization of education.

This thesis presents a case study of Microsoft Corporation’s Partners in Learning (PiL) program, an example of transnational policy authority in education, with two embedded case studies of PiL in Jordan and South Africa. The constructivist and rationalist approaches highlight the changing nature of governance through the cultural and strategic shifts that led to Microsoft’s policy role in education. Microsoft’s strategic profit interests and its corporate-social-responsibility aspiration to play a policy role in education influenced its educational footprint. From a top-down perspective, Microsoft used supranational forms of power by implementing its global PiL blueprint through similar PiL programs worldwide. From a bottom-up perspective, Microsoft used “localization practices” by engaging different subnational agents and used different strategies to gain footholds in two very different political and policy contexts. Microsoft’s top-down and bottom-up approaches link the supranational policy arena to the subnational or subgovernmental. Microsoft’s economic power and strategic engagement gave it entry into education. It gained expert authority from its extensive history and experience in education. Its expert authority was experessed through strategic relationship building through diplomacy and partnerships, policy networks, and the sharing of best practices. The company was however not able to claim absolute legitimacy because of resistance in both countries. This thesis highlights that at the governmental level, sovereignty does not disappear when transnational corporations become involved in education at the national level. Instead, nation- states become strategic sites for the restructuring of global policy roles. The Jordanian government became a public facilitator, by working with Microsoft to implement a stand-alone PiL program. The South African government became a public integrator, by implementing the PiL program within government policies and programs. Power was also redistributed within both countries, moving away from government education officials towards the monarchy in Jordan and the presidency in South Africa. The findings of the study highlight the need for corporations engaged in public education to be governed within instituted accountability measures, for appropriate partnership frameworks, and for governance tools that can both effectively engage companies in education and ensure that they work within common goals and values set out by international education organizations.
