摘　　要：秦一厂30万千瓦级发电机于2018年实施增容改造,功率提升至350 MW,在正式商运前开展发电机进相能力分析与试验,试验数据将作为发电机今后进相运行的重要依据。本文对功率提升后的发电机进相深度进行计算,对试验目的、试验方法、限制条件、安全措施进行阐述和分析,将试验结果与1993年进相试验数据进行对比分析与评价,确定发电机经过增容改造以及电网容量扩张,使得发电机进相能力增强,可为电网做出更大贡献。The power of the 300 MW Qinshan I was raised to 350 MW in 2018.Before the official commercial operation,the analysis and test for the under-excitation operation capability of the generator will be carried out.The test data will serve as an important basis for the under-excitation operation of the generator in the future.In this paper,the under-excitation depth of the generator after power raising is calculated.The test purpose,test method,restrictive conditions,and safety measures are elaborated and analyzed.After the test results are compared with 1993 data,it is determined that the under-excitation operation capability is enhanced after power raising and network capacity expansion,and can make a greater contribution to the grid.
