摘　　要：由于电力系统的动态行为表现出混杂系统所共有的特征,使得电力系统负荷侧电压控制研究变得复杂。描述了混杂理论和可编程赋时Petri网(PTPN)的基本思路,然后基于混杂理论,用可编程赋时Petri网的方法对有载调压器分接头的调节进行了混杂建模。最后将所建模型放在一个简单的单机系统中进行仿真,得到母线电压以及离散变量变化的曲线,结果表明建立的模型是合理的,对延迟电压崩溃起到了积极的作用。Since the dynamic behaviors of power system represent the characteristic of hybrid system, it is difficult to research the voltage control on the load side. The paper describes the basic thoughts of hybrid theory and programmable timed Petri nets(PTPN). Based on hybrid theory, the hybrid model of regulation for OLTC′s taps is built by the way of PTPN. Finally the model is simulated in a simple single-generator system, and the changing curves of bus voltage and its discrete variable are obtained. The result shows that the model is reasonable, and it can take positive effect on postponing the voltage collapse.
