Simulation Model Study And Development Of Blocking Power System

The figure simulation of power system is a complex subject of computer science and computational mathematics and control theory and power system application technology. Its essential is that it study work characteristic of system in a definite-time by mathematical model. In other words, it studies system by the models. The figure simulation of power system belong to a continuous system simulation, so, mathematical models generally include a dynamic description of elements and a mathematic description of circuits. Namely, it comprises differential equation and network equations. Base on simulation purposes, in addition to deducing a carefulmathematical model, the tasks of modeling involve selection styles and scales and interrelations of all kinds of elements. The aim of establishing the models are serves simulation. The models can consider extra fine, but in relevant applications of simulation, corresponding computational complexity enhance also. Sometimes, the models are very difficult to realize. So, it is a very important work for modeling assumption and the models reduction.The text's main works involve to establishing mathematical models and come true models' algorithmization and found blocking simulation models and simulation application.The tasks of establish mathematical models of power system bases on similarity principle to construct mathematic description of the models. Main mathematical models include generator system and prime mover system and network and failure and load of static and dynamic andtidal current calculation. In process of establishing the models, we need think over the models condition of application and reduction. To the system composing subsystem, assure hole hog mathematical models, for example, unified coordinate system, etc. System models have explicit logical relation to mathematic description. The models' constitution should be propitious to realize computer algorithm. Mathematical models algorithmization can realize easily through choosing corresponding models and computer language. In the course of algorithmization, we should select arithmetic with high numerical stability and controlling error and computational effort little and saving memory space.The text recurs to blocking platform, i.e., power system simulation support system BLINK. BLINK system is capable of treating separate blocking to arithmetic. It can realize models' build and combination. And recurring to BLINK system can carry through blocking problem. Thelast dynamic simulation's example shows effectiveness of blocking modeling. In future, the blocking modeling will can be an effective implement and method for large-scale power system simulation.
