摘要(Abstract):

随着新能源技术的发展,海上风电因其高效且不占用陆地空间的优点得到业内的高度重视。海上风电工程陆上计量站及海上升压站受电启动是风电场建设的一个重要节点,影响着整个工程的进度和质量。针对目前海上风电工程受电启动阶段带负荷试验缺乏可靠手段的问题,研究了一种新的海上风电工程受电启动带负荷试验方法:在风力发电机组处于安全停机状态时,闭锁机组侧换流器,电网侧换流器根据试验需求灵活控制输出电流的幅值,进而满足海上升压站受电启动试验的要求,实现一次设备、二次回路、计量仪表、继电保护及自动化装置的整套校验。现场试验结果表明:该方法成功实现了并网前海上升压站受电启动带负荷试验,完善了海上风电工程受电启动试验方法,降低了后期机组并网试验的风险,提升了调试质量,缩短了试运工期。
With the development of new energy technology, offshore wind power attracts more attention due to its high efficiency and land inoccupancy. Power-receiving startup of on-shore metering stations and off-shore booster stations is a key node of wind farm construction, influencing the entire schedule and quality of the project. Aiming at the lack of reliable means to carry out the on-load test during power-receiving startup of the offshore wind power project, this paper develops a new method. In the case of safe shutdown of wind turbine units, the turbine-side converter is switched off and the grid-side converter controls output current amplitude as the test requirement to meet the requirement of power-receiving startup test of off-shore booster stations and complete the verification of primary equipment, secondary circuit, metering instrument, relay protection and automation equipment. The field test result shows that this method can complete the on-load test for power-receiving startup of off-shore booster stations before grid integration, better power-receiving startup test method,reduce the risk of grid integration test of units, promote the commissioning quality, and reduce the commissioning time.
