Abstract
Power system simulation software has become an essential tool for today’s power system engineers. The accurate simulation of various components of the power system helps power engineers comprehend, design and analyze complex power systems. In the present deregulated energy industry scenario, where power systems are operated close to their operating limits, understanding the complexities involved has become even more crucial. Software models of various components of the power system in the form of equations representing their operating characteristics have been used by academicians, consultants and manufacturers. Very accurate software models of many power system components, which represent these equations, are available today. However, software models of some components such as protection relays, controllers, etc., are not available to power engineers. The main reason for this being that modeling of these components require very accurate design details and these details are not available in the open domain. Manufactures are not willing to divulge the design details of their products for proprietary reasons. In this thesis, a new paradigm based on a client-server approach is proposed, which elegantly solves this problem. The setup for the proposed solution consists of two parts: the client side on the customer end, which has the entire simulation package except the model from the manufacturer and the server side on the manufacturer’s end, which has the software model of their product. The two ends communicate through the internet using an appropriate client-server interface. Thus, both the manufacturers’ apprehension to divulge their design details can be alleviated and the models can be made available to the users at the same time. A software model of a commercial protection relay was developed. The setup required to verify the proposed client-server paradigm was developed and the proposed solution was tested with the developed model. Various issues in 111 implementing the proposed solution have been addressed. This new approach will have a significant impact on the way software models of commercial products are used for power system studies. The power engineers can perform more accurate simulations, which help them to comprehend and design more complex power systems.
