海外华龙一号发电机整组启动试验浅析

Brief Analysis of the Whole Unit Starting Test of Overseas Hualong No.1 Generator

华龙一号核电机组并网时的丝毫偏差都会对电网的频率、电压的安全性和稳定性造成冲击,故并网之前必须严格按照要求进行发电机整组启动试验,借此查找和解决问题。通过介绍和分析海外华龙一号某机组发电机整组启动试验中的短路试验、空载试验等重要试验,发现并解决发电机各环节潜在的问题,为后续华龙一号的调试工作提供借鉴。

Any deviation during the grid-connection of Hualong No.1 nuclear power plant will affect the safety and stability of the power grid's frequency and voltage.Therefore,it is necessary to carry out the start-up test of the whole generator unit strictly in accordance with the requirements before grid-connection to find and solve the problems.The important test methods such as short circuit test and no-load test in the whole starting test of a generator of an offshore Hualong No.1 generator unit are introduced and analyzed.The potential problems in each link of the generator are found and addressed,and references for the subsequent debugging work of Hualong No.1 are provided.
