| 摘 要： | 闪变是电能质量的问题之一，对其进行定位研究，可以明确供电方、用电方的责任，为综合治理提供了一定的理论依据。研究了闪变产生的原因及其在变压器间的传递规律。闪变源支路负荷将引起所连接的母线电压波动，但其通过的电流受负荷本身特性影响，与母线电压关系不大，而非闪变源支路负荷通过的电流取决于母线电压。根据这一特点，通过计算母线电压和支路负荷电流相关度的新方法，能够实现多个支路负荷的闪变源识别，该方法简单、易行，满足准确度的要求。

| Abstract: | The flicker is one of the important aspects of the power quality. Identification of the flicker sources is a critical demand of improving power quality. It has great significance on ascertaining the responsibility of customers and utilities. The flicker causation and the passing law between transformers are discussed in this paper. The flicker load can cause the voltage fluctuation in the bus. Its current is affected by the characteristics of the load and not related to the voltage fluctuation. Otherwise, t... |
