| 摘 要： | 厂用电系统中一般带有集中电动机负荷，异步电动机启动会引起母线电压严重的波动。系统装设静止无功补偿器(SVC)是有效解决电压质量问题的方法之一。文中采用配有自动电压调节器(AVR)的发电机励磁与系统母线装设SVC的方法，SVC采用闭环控制，研究其对电压稳定和无功补偿的效果。通过对某电厂厂用电系统的仿真计算表明，该方法可提高厂用电电压的水平，并且缩小了异步电动机的启动时间，减少了大型异步电动机启动对系统母线电压的波动和无功功率的冲击。

| Abstract: | The electric auxiliary system usually consists of condenser motor loads, and the starting of inductor motors can cause the problem of bus voltage fluctuations. Application of SVC is one of the methods dealing with the problem. This paper studies the effect of SVC or AVR in improving system voltage stability and reactive compensation. The simulation results prove that voltage level of electric auxiliary system is improved when SVC and AVR are installed at the power station, starting time of inductor motors and impact of reactive power are minimized, also the bus voltage fluctuation is damped. |
