应对冲击性负荷接入的SVC应用分析

Analysis of SVC Application to Deal with Impact Load

冲击性负荷的接入对电网的安全稳定运行造成了一定的挑战。为分析SVC在含冲击性负荷的电网中的应用效果,首先介绍了静止无功补偿装置的原理和控制特点;其次提出了一种SVC的定无功控制方法,以保证无功就地平衡;最后根据实际录得的运行数据,建立仿真模型,对比分析了传统AVC站端控制策略与SVC定无功控制应对冲击性负荷接入的控制效果。仿真结果表明,在含有冲击性负荷的变电站中,应用SVC相比传统控制方法在稳压、降损等多个方面都具有更好的控制效果。

More and more impact load access to the substations, which have caused some challenges to the current power grid. This paper introduces the principle and control features of Static Var Compensator, and analyzes its role and application in response to the impact load. In addition, according to the actual recorded of the active and reactive power, we compared the traditional AVC control strategy and the SVC reactive power control of a given impact load control effect.
