Research On Method Of Modeling For Electrical System On Power Station Simulator

With the development of high parameters large capacity’s power plant units and the increasing automation level of power plant, safe and stable operation of the unit is the most important index of power system. It is undoubted that the reliability and economy of electric power production safety, higher requirements, plant operators have to continuously improve their professional knowledge,skills and handling unexpected failure strain capacity, they can adapt to the new situation of the work environment better, so a full training is essential.Simulator is an installation with computers as its core which is developed to simulate turbo generator and used to train operators. Electric simulation system is an important part of simulation software of power plant. Simulation of power plant has been applied widely in order to improve effectively operators’ knowledge, operation skills and their ability to response the emergency. The electrical system is an integral part of thermal power station simulator. Basing on this background, modeling and simulation of thermal power plant units’ electrical system study a deep research in this paper.This article focuses on the study of the electrical system model methods. The study is based on modular modeling.First the study discusses the process, the composition and and major equipment of the thermal power plant electrical system. Comprehensive analysis of the electrical system contribute to a reasonable division of the module. Then, derive a mathematical model based on the mathematical theory. Electrical system of power plant as study object, is divided into different types of blocks. Then every part mathematical model is established. On the basis of this theory, describes corresponding algorithm module in the algorithm library. Using these algorithms modules built the logic model according to the simulation needs. According to site data and other information of the power plant, complete the commissioning of the electrical system simulation model to meet all the related parameters’ steady-state accuracy requirements of the errors between the actual’ data and simulation system’ data.
