摘　　要：随着新型电力系统的不断发展,风电、光伏等新能源在电力系统中的占比越来越大。这对常规水电机组,尤其是大型混流式机组的运行方式提出了新要求,需要机组具备调相功能,以给电网提供足够的无功支撑,维持系统电压稳定,提升电网供电质量,促进电网安全稳定运行。基于此,以某大型混流式水轮发电机组为例,详细分析具备调相功能的混流式水轮发电机组的关键结构设计要点,以期为其他在建机组的设计和已建机组的调相改造提供参考,为推动新型电力系统发展做出更多贡献。With the continuous development of new power systems,the proportion of new energy such as wind power and photovoltaic in the power system is increasing.This puts forward new requirements for the operation mode of conventional hydropower units,especially large mixed-flow units,which need to have phase modulation function to provide sufficient reactive power support for the power grid,maintain system voltage stability,improve the power supply quality of the power grid,and promote the safe and stable operation of the power grid.Based on this,taking a large mixed-flow turbine unit as an example,the key structural design points of the mixed-flow turbine unit with phase modulation function are analyzed in detail,in order to provide references for the design of other units under construction and the phase modulation transformation of existing units,and make more contributions to the development of new power systems.
