【摘要】 本文在对混杂系统基础理论进行系统描述的基础上,阐述了混杂电力系统的基本概念。论文提出了用Modelica计算机仿真语言按面向对象技术原则设计混杂电力系统仿真平台的思想,建立了包含发电机、输电线路、负荷、变压器、带分接头的有载调压器、可投切电容器组、低电压切负荷装置、电气制动、快关汽门装置等元件或控制器的混杂电力系统机电暂态过程仿真模型库。用可编程赋时Petri网方法建立了产生混杂行为的控制器模型。最后对所建元件模型进行仿真分析,结果表明平台可以反映电力系统动态过程中的混杂特性。本文可以为今后建立电力系统的全动态仿真平台提供借签。更多还原

【Abstract】 This paper presents the basic concept on the base of systemic description on hybrid system basal theory. The dissertation mainly expounds the thoughtway of designing hybrid power system simulating flat roof by the principle of object-oriented technique through a computer language Modelica. The flat roof can emulate the eletromechanical transient process of hybrid power system which includes generator, transmit-line, load transformer, on-load transformer controller with tap, switchable capacitor groups, low- voltage removing load device, dynamic-brake devic, fast closing vapor door equipment and so on. Controllers which produce hybrid action are set up by the way of programmable timed petri nets. Finally, the biulded component models are simulated, result displays that the flat roof can truly reflect power system’s bybrid characteristic. The paper can provide reference for the power system whole- dynamic emulating flat roof’s establishment.更多还原
