摘要
基于PSASP仿真平台,搭建了包含陕北~武汉特高压直流的2019-2020水平年电网模型,分析了特高压直流接入对电网短路电流、潮流、暂态稳定的影响,讨论了不同约束条件下湖北电网对直流功率的消纳能力。研究结果对湖北电网规划和运行具有一定的指导作用。
The influence of Shanbei-Wuhan UHVDC transmission project on Hubei grid is studied in this paper. Simulation model of Hubei power grid in 2019-2020 is constructed based on PSASPwhich concluded Shanbei-Wuhan UHVDC project. The influences of UHVDC on short-circuit cur-rent, power flow and system stability of Hubei power grid are analyzed. DC electric power accommodation capacity of Hubei power grid in different constrained conditions is calculated. This studyhas some reference value for the planning and operation of Hubei power grid.
