Study on the electrical characteristics of the UHV system with double-circuit transmission lines on the same tower
In order to analyze the electric characteristics of the UHV double circuit transmission line system , a simulation model is built on the Real Time Digital Simulator (RTDS) based on the design parameters of the very first UHV double circuit transmission line system in China .To study and master the electric characteristics of the UHV double circuit transmission line system thoroughly special compare between the UHV double circuit transmission line system and the UHV single line system and the compare between the UHV and EHV double circuit transmission line system model are made . It can be concluded the double circuit transmission line system has the following features: The ingredient of the harmonics in the fault current and voltage are redundant .There are large DC components included in the fault current and the decaying process are very slow. The amplitude of the recovery voltage are quite high ,and the beat frequency are less visible compared to the EHV system. The capacitance current of the system are high before the compensation . The fault current with high resistance are much higher in the near side than in the far side.
