风电集中接入对西北电网运行影响及对策研究 程林 范越 张振宇 牛拴保 张小奇 （西北电网有限公司，陕西省西安市，710048 ） Study on the safety and stability problems and solutions in Northwest power grid with large-scale wind farm connection (Northwest China Grid Company Limited, Shanxi Xian, P.R. China,710048) Abstract: In the article in view of the northwest Key word: Networking project; 750kV electrical principal network and the Xinjiang electrical network network; Movement way; Wind electricity; networking project production initial period, the Transportation limit; Stable deep research northwest electrical network main security stable question, specially on the networking 摘要:文中针对西北主网与新疆电网联网工程投产 channel Hexi area Jiuquan wind electricity base 初期，深入研究了西北电网主要安全稳定问题，特 ground wind electricity centralism turning on to the 别是联网通道上河西地区酒泉风电基地风电集中接 system safety stable influence, the quantification river 入对系统安全稳定性的影响，量化了河西风电与同 westerly wind electricity and the co-content thermal 容量火电机组接入系统对联网通道输电能力差别。 power unit turns on the system to the networking 研究结果表明，由于风电机组出力的随机性和间歇 channel transmitting capacity difference. The findings 性，风电集中接入将引起电网有功功率随之大幅度 indicated that as a result of wind electrical machinery 波动，进而造成河西 750 千伏通道电压控制困难， outputs randomness and the intermittence, wind 并对系统调频、调峰及调度运行带来挑战；但通过 electricity centralism turning on will cause the 提出相应技术措施，实施和完善运行控制策略和措 electrical network active power along with it large 施，合理安排电网运行方式，严把风电并网关，确 scale fluctuation, then causes the Hexi 750 kV channel 保风电机组抗频率、电压扰动特性满足相关规定要 voltage control difficulty, and to the system frequency 求，以最大限度的发挥联网通道输电能力。 modulation, the peakload and the dis
