摘要

研究了可变速抽水蓄能机组在抽水工况下采用定子绕组短接方式的零速自启动方案及其启动特性。文中分析并建立了在定子绕组短接情况下变速机组的数学模型、相量图以及机械特性。在此基础上

以转子电流与定子磁链为状态变量构建了状态观测器

提出了基于状态观测器的闭环自启动方案

并通过仿真对该方案在启动时间、转矩特性、估计精度等方面的性能进行了定量的分析

结果表明该方案具有良好的启动性能以及鲁棒性。

Abstract

This paper focuses on the self-starting strategy of variable speed pumped storage units(VSPSU)by the shorting machine stator. Firstly

the mathematical model

phasor diagram and characteristics of VSPSU are proposed while the machine stator is being short-circuited. Then a robust stator flux observer is created for the self-starting strategy with stator flux oriented control to accelerate the rotor for synchronization. The starting time

torque characteristics and estimated accuracy of this strategy are quantitatively analyzed by simulation. The results show that the strategy has good starting performance and robustness. This work is supported by Fundamental Research Funds for the Central Universities(No. 2014B04614)and State Grid Corporation of China.
