Research on the Configuration of Reactive Power Compensation Equipment for VSC-HVDC Transmission System in New Energy Base
One of the important ways for China's energy generation to connect to the grid is through voltage source converter-based high voltage direct current(VSC-HVDC)transmission of large-scale wind and solar renewable energy bases.Due to the weak voltage support capability of the renewable energy base,the system stability is seriously affected.Static synchronous compensator(STATCOM)and condenser configuration are effective means to improve system stability.This article proposes a two-stage configuration method including STATCOM and condenser.In stage 1,the system side voltage support is achieved by configuring STATCOM.Stage 2 ensures the transient stability of the system through the configuration of the condenser.Based on the PSCAD/EMTDC simulation platform,a simulation model for the VSC-HVDC transmission system of the renewable energy base is built,and the effectiveness and rationality of the proposed method are verified.
