摘要
当已知电能计量装置误接线方式时,本文提出了两种正确计算实际消耗电量的方法:一是采用解方程组求实际消耗电量与错误总电量关系的方法;二是通过分解功率表达式求实际消耗电量与错误分相电量关系的方法。这两种方法可在不具体计算功率因数的前提下,求出实际消耗电量,使退补电量的计算更加正确,符合实际。
This article discuss two calculate methods of computing actual consumption electrical energy truly under the condition of knowning the wrong wiring way about Electrical energy measuring device： one is the method using the square distance set ,and solve actual consumption electrical energy and wrong electrical energy; Two is the method of resolving the power expression type to solve actual consumption electrical energy, and wrong electrical energy . These two kinds of methods can solve actual consumption electrical energy without knowing the power factor. These calculate methods can solve the wrong electrical energy better, match physically.
