摘要/Abstract

摘要： 针对供电型电压互感器供电电压随负荷而变化的实际情况，介绍了一种基于辅助互感器串联补偿技术的供电电压补偿方法。以一台额定一次电压为110√3 kV，额定容量为60 kV·A的单相供电型电压互感器为例，计算了其供电电压及供电容量随负荷容量及功率因数的变化率。依据变化率，设计了基于辅助互感器的供电电压自动补偿回路，可实现对供电电压±4.4 V、±8.8 V、±13.2 V、±17.6 V、±22.0 V、±26.4及±30.8 V的补偿量。分别对功率因数cos φ=1和cos φ=0.89（感性）2种情况的不同负荷容量下供电电压补偿效果进行验证，试验结果表明：增加了辅助互感器自动串联补偿回路后，供电型电压互感器的供电电压变化率由–1.80%~11.36%提高到了–3.000%~0.045%，完全满足标准对单相220 V供电电压质量的要求。采用辅助互感器的自动串联补偿技术，可以实现对供电型电压互感器供电电压的补偿，解决了由于农村负荷功率因数低，高峰负荷期供电电压偏低的问题，对提高用户电压质量提供了保障。

Abstract: In view of the fact that the supply voltage of power voltage transformer varies with load, this paper introduces a method of supply voltage compensation based on series compensation technology of auxiliary transformer. Taking a single-phase power supply voltage transformer with rated primary voltage of 110 / 3 kV and rated capacity 60 kV·A as an example, this paper calculates the variation rate of power supply voltage and capacity with load capacity and power factor. According to the rate of change, an automatic compensation circuit of power supply voltage is designed based on auxiliary transformer, which can realize the compensation of power supply voltage (+4.4 V, +8.8 V, +13.2 V, +17.6 V, +22 V, +26.4 and +30.8 V). The power factor cosφ=1 and cosφ=0.89 (inductive) are used to verify the power supply voltage compensation effect under different load capacities. The experimental results show that the power supply voltage change rate of the power supply voltage transformer increases from -1.8% ~ + 11.36% to -3% ~ + 0.045% after adding the automatic series compensation circuit of the auxiliary transformer, and the requirements for the quality of single-phase 220 V power supply voltage can be satisfied. The automatic series compensation technology of auxiliary transformer can be used to compensate the supply voltage of power supply voltage transformer, which solves the problem of low power factor of rural load and low supply voltage in peak load period, and can provide a guarantee for improving the voltage quality of users.
