【摘要】：采用转子交流励磁结构的变速机组在抽水工况下亦可进行功率调节,有效地解决了常规定速机组抽水工况功率不可调节,调度运行模式单一的缺点。合理的监控流程是保障机组启动成功率的关键环节,目前国内还没有针对可变速机组的监控流程的探讨。通过分析对比变速机组与定速机组的机械结构与励磁控制方向,结合常规机组的调试经验,提出了可变速机组水泵方向启动的三种可行方式的监控流程,即静止变频器启动,背靠背启动和自启动。前两种启动方式的监控流程是在定速机组启动流程的基础上做出适当修改。自启动方式的监控流程则是根据变速发电电动机励磁系统的原理,结合电气及水机等分系统的工作方式,提出的一种可行的监控流程的设想。
[Abstract]:The transmission unit with rotor AC excitation structure can also adjust the power under pumping conditions, which effectively solves the problem of unadjustable power under pumping conditions of conventional fixed-speed units. The disadvantages of single dispatching operation mode. Reasonable monitoring flow is the key link to ensure the success rate of unit start-up. At present, there is no discussion on the monitoring flow of the variable speed unit in China. By analyzing and comparing the mechanical structure and excitation control direction of the transmission unit and the fixed speed unit, combined with the debugging experience of the conventional unit, The monitoring flow of three feasible ways to start the water pump direction of the gearbox group is put forward, that is, the static frequency converter starts. The monitoring flow of the first two startup modes is to make appropriate modifications on the basis of the starting process of a fixed speed unit. The monitoring flow of the self-starting mode is based on the principle of the excitation system of the variable-speed generator motor, and the monitoring process of the self-starting mode is based on the principle of the excitation system of the variable-speed generator motor. Combined with the working mode of electrical and hydraulic sub-systems, this paper puts forward a feasible scheme of monitoring flow.
