The Research Of Electrified Wire Netting And Electric Energy Mass Harmonic Monitors Systematic In Cang Zhou City

The Cangzhou electrical network is in south of Hebei net terminal. The system is relatively small and the withstanding disturbance load's ability is bad. In this paper, firstly, it studies the Cangzhou electrical network to the electrical energy quality request, and then it analysis the influence of the harmonic and the negative sequence to the Cangzhou electrical network. Secondly, it establishes the harmonic of the electrical power system parts as the transmission lions, transformers, capacitors and other compensation parallel power system components in asymmetric circumstances, and the power system can be calculated in different frequency components of the equivalent circuit parameters. On that basis, the paper analysis the harmonics component systematicly and quantitatively in Cangzhou power network, also it provides accurate and reliable data to the harmonics grid management. According to the results, it researches the power quality harmonics monitoring system of Cangzhou and analysis the function which produces to the electrical network, so that carried on the harmonics comprehensive government for the Cangzhou electrical network to build the foundation.
