二次压降自动补偿仪的数学原理及实现

Mathematic Principle and Realization of the Secondary Circuit Voltage Drop Automatic Compensator

从电压互感器二次压降的比差和角差出发，建立了补偿二次压降的两个数学公式，并以单片微型计算机为核心构成一个通信、计算和输出控制的闭环系统，实现了补偿的目的。实践表明，该补偿仪原理正确、设计合理，达到了部颁ＳＤ１０９－８３标准。

Constructs two mathematical rules from voltage error and the angle of deviation of secondary circuit voltage drop of the voltage transformer. An automatic compensator was designed using a single chip microcomputer and these two rules. Experiments prove that the principle is correct and that the automatic compensator achieves the standard of SD109 83.
