用制动电阻和补偿电容进行电力系统快速再同步控制

Fast Resynchronization Control in Power Systems Using Braking Resistors and Comopnsating Capacitors

本文提出一种电力系统再同步的快速控制方法。这种方法交替使用并联制动电阻和串联补偿电容,有效地减少了滑极数和可靠地保证滑差过零之后的再同步成功。开关切换功角按最大能量耗散和最短路程准则设计.所提出的策略用精确数学模型的数字仿真予以验证。

A new method of fast resynchroniztion control in electric power systems is presented in the paper.The method can efficiently decrease the slip-pole number and reliadly succeed in resynchronization using braking resistors and compensating capacitors alternatively.The power angle for switching is de- signed according to the principles of maximum energy consumption and of minimum distance.The control strategy presented in the paper is proved by digital simulation using accurate mathematical models.
