摘　　要：在同步发电机进相试验导则基础上,给出了以发电机功角为约束条件的进相深度限值计算方法。它研究了功角限值工况下系统电抗对系统静态稳定的影响,对机端电压和定子电流是否越限进行校核,并给出越限后最大进相深度修正方案。以瑞金电厂1号机组为算例,在不同的升压变高压侧母线电压工况下,绘制了机组进相深度限值随有功出力变化的PQ曲线。考虑进相试验约束条件的计算结果可以为试验人员控制进相深度提供参考,以保障试验过程中机组的安全稳定运行。Based on the leading power factor test guidelines of synchronous generator,the calculation method of leading power factor depth limit constrained by generator power angle was presented,and the impaction of system reactance on system static stability with power angle limited was studied. Meanwhile,the values of terminal voltage and stator current were checked and the modification of leading power factor depth limit was given if these values were overlimit. Taking 1#generator of Ruijin thermal power plant for example,the PQ curves of leading power factor depth limit changing with active power were showed under different system voltage conditions. The results considering constraints of leading power factor test could provide references for experimenters to control leading power factor depth so as to ensure the safety and stability of generator in the tests.
