Abstract
With the capacity of new energy resources such as wind power and photovoltaic in Zhangbei region increasing rapidly, the reliable transmission and consumption capabilities of large-scale and high-proportion new energy resources are urgently improved. Considering the advantages of the VSC-HVDC transmission technology, Zhangbei project is designed as symmetrical bipolar system which adopts half-bridge modular multi-level converter (MMC) topology and overhead lines for power transmission. In this paper, a system scheme was presented, and some results were provided. Meanwhile, a novel modular cascaded hybrid DC breaker concept was proposed, and 500 kV VSC valve and DC breaker prototype were developed to meet the requirement of the Zhangbei four-terminal DC grid.
