混合式无功补偿在用户电压质量治理中的研究

Research on Hybrid Reactive Power Compensation inUser Voltage Quality Renovate

供电电压质量是配电网稳定运行中的重要综合性指标之一。随着经济发展,用户的用电量日益增加,从而导致用电高峰时期的“低电压”问题尤为突出。本文通过分析串联补偿、并联补偿以及混合补偿对提升线路末端电压的影响,提出一种混合式无功补偿在用户电压质量治理方法。该方法在综合考虑了线路和用户用电特性的前提下,可以有效地提升用户用电电压、提高线路输送能力。

The quality of the user’s power supply voltage is one of the important comprehensive indicators in the stable operation of the distribution network.With the development of the economy,the user’s electricity consumption is increasing,which leads to the“low voltage”problem during the peak period of power consumption.In this paper,by analyzing the effects of series compensation,Shunt compensation and hybrid compensation on the voltage at the end of the line,hybrid voltage compensation method for user voltage quality is proposed.The method can effectively improve the user’s power consumption voltage and improve the line transmission capability under the premise of comprehensive consideration of the line and user power characteristics.
