PMU Application Prospect In The Distribution And The Optimized Allocation Of Research

Phasor measurement unit in the distribution state estimation, fault location, the circuit parameters, power quality monitoring and anlysis distribution of the whole networks harmonic are an important aspects of application value. Therefore, the optimized allocation of distribution PMU is a research focus.First introduced PMU configuration optimization methods, and compares their advantages and disadvantages.Then establiah mathematical model of the PMU optimized allocation according to distribution characteristics. With the 0-1 integer programming combining LINGO software solution.This method considering the entire system observable and make the number of the PMU as less as possible, can achieve the desired target.And to the no configuration with harmonic state estimation, Second harmonic state estimation method to estimate the unknown nodesis in this paper,This paper puts forward some positive (or to) and underdetermined equation respective adopted Cholesky decomposition method and orthogonal transformation.With MATLAB simulation verified.
