MODELING AND ON-SITE EXPERIMENTS OF SHUNT CAPACITOR COMPENSATION METHOD FOR DEICING OF 66KV POWER LINE

摘要：

An EMTP-ATP model and a MATLAB model of 66kV double line network are built and simulated. By applying shunt capacitor compensation method for de-icing 66kV overhead transmission line within the models, the simulation results show an increase of the rms line current to 650A for the de-icing line which leads the cable temperature to increase. A COMSOL model for LGJ-120/20 cable is also built to simulate the temperature distribution of current-carrying ice covered cable. The simulation results show that the cable coated with 3cm thickness ice sleeve can be deiced, which the surface temperature of the cable can be increased to above 310k after 40 minutes. Through the on-site experiment in Mishan primary substation 66kV transmission line, the real-time data were matched by both EMTP-ATP and MATLAB simulation results, which verified the effectivity and feasibility of the shunt capacitor compensation deicing method.
