利用电导比实时监视开关运行性能

Using Conductance Ratio to On-line Monitor the Switch Performance

通过对开关网络的潮流分析,得出实际运行条件下计算开关网络中各开关电导比的公式和求解方法,并给出了程序框图。求解出的电导比,可以为实时监控开关运行性能提供一种量化的依据。同时在输入潮流已知的条件下,利用电导比可求解出各开关的潮流分布,为分析开关的使用寿命等性能提供了数据依据。

Through analyzing the power flow in a switch network,a calculation method and formula and its program block diagram of conductance ratio of every switch are put forward in this paper.The conductance ratio can be used as a measurable criterion in monitoring switch performance.Under the condition of given power flow,the power flow distribution of different switches can be calculated out using conductance ratio.So the problem of switch lifetime performance data well be determined.
