应用于负载侧的分布式电压控制的仿真研究

Simulation of Distributed Voltage Control Applied to Load Side

负载侧无功装置具有储能少、控制简单等优点,应用于负载侧来平衡由无功变化引起的电压波动。在MATLAB/Simulink中搭建了一个负载侧无功装置的仿真模型,观察负载侧无功装置接入前后的电压波形的变化情况,来说明负载侧无功装置的稳压能力。首先观察无功损耗增加或减少时的稳压能力,然后观察无功损耗随机变化时负载侧无功装置的稳压能力。仿真结果表明,负载侧无功装置具有很好的稳压性能。

With advantages of without a lot of storage and fast response,reactive power device to load side is applied to the load side for balancing voltage fluctuation caused by reactive power.In order to proof the ability of regulating voltage of reactive power device to load side through observing change in the voltage waveform with and without it.A simulation model of the compensator in MATLAB/Simulink is proposed.Firstly,observe the effectiveness of adjusting voltage while consumption of reactive power is increased or decreased.Finally,observe the ability of balancing voltage when consumption of reactive power is changed randomly.
