Research On Mixed Simulation System Of Power Quality

With the fast development of national economy,power load is rising rapidly,especially for the wide application of non-linear load and time-variant load in power system. Waveform of electrical current and voltage is significant distorted and the problem of quality of power supply becomes serious. It can threaten the security of power system and reduce the life of electrical devices. In this paper we research on the software of mixed simulation system of power quality.The software can studying and analyzing how the harmonious current and voltage is scattered in the distribution system; studying and comparing effects of the control components and evaluating optimize configuration scheme of control components in the network Simulation System..This paper is made up of six chapters. It is started from the basic concepts ,classes and the standards of Power Quality,then bring forward the concept of Mixed Simulation System of Power Quality . The thesis applying the most up-to-date Object Oriented Technique developed,develops a pure object oriented modeling system with high expansibility and reusability performance and applies latest object oriented techniques such as object oriented designed patterns,software architecture and framework and component theory to power system software developing. The software is designed by integrated application of latest OOA/OOD methods,described by UML and implemented. The developing platform is the latest and efficient tool Visual C++-.Net and Visual C#. The software platform can input and save wiring diagram of location region,calc and analysis the harmonic power flow,figure displaying,report print,publishing data and so on.
