| 摘 要： | 传统的根据无功功率的定义来计算静止无功补偿器(SVC)系统中的无功功率的方法难以满足快速响应要求,因此本文采用瞬时无功理论来实现SVC系统中无功功率的计算和检测。文中分析了瞬时无功理论的原理,在此基础上推导出SVC系统中瞬时无功功率的计算公式,然后采用滑动平均窗的方法实现对无功功率的检测。通过仿真实验实现SVC系统无功功率的计算和检测,仿真结果表明,算法能快速有效地检测SVC系统中的无功功率,为设计SVC中无功功率的检测和控制系统提供了理论依据和实现方法。

| Abstract: | The traditional methods based on definitions of reactive power can not fulfill the demand,so the paper employs the instantane- ous reactive power theory to detect the reactive power in SVC system.The paper analyses the principle of instantancous reactive power theory,and deduces the formula to calculate the instantaneous reactive power in SVC system,and employs a sliding window to calculate the average reactive power.The paper applies the new method by simulation,the results of which show that the method is efficient in detecting reactive power in SVC system and thus provides application in designing the monitor and control system of SVC. |
