摘要 大型同步电机瞬态参数的测量一般通过三相突然短路实验进行,实验过程复杂且存在一定的危险性。以静止频率响应实验、信号输入实验等为代表的静止实验方法可在一定程度上解决安全性问题,但此类方法必须进行转子预定位,对于大型同步电机实施难度较大,且定位误差也会影响测量的准确性。针对上述问题,该文基于信号输入实验原理,提出了一种任意转子位置下的同步电机全参数辨识实验方法,其中包括一种扩展至频域的Dalton-Cameron变换方法,以此为基础提出任意转子位置下的实验方案并加以应用分析,实现了dq轴参数的同时辨识。第三代非支配排序进化算法(NSGA3)被用于时域拟合过程以获取所需电枢电流响应信号的表达式。最后,通过对一台动态模拟实验样机进行实验,验证了所提出的参数辨识方法的有效性和准确性。该文提出的实验方案及参数辨识方法不仅适用于采用其他形式信号的信号输入实验,同样可为其他类别的静止实验方法提供参考。

Abstract:The measurement of transient parameters of large synchronous machines is generally carried out by a three-phase sudden short-circuit test, which is complicated and has certain dangers. Standstill test methods, such as static frequency response tests and signal input tests, can solve the above problem to some extent. However, such kind of tests must align the rotor with specific positions, which is difficult to implement for SMs of high capacity, and the positioning error also affects the accuracy. Aiming at the above problems, this paper proposed a novel full parameter test method based on signal input test for arbitrary rotor positions. A novel expanded Dalton-Cameron transformation was proposed and the corresponding test scheme was also given and analyzed, so that d and q axes parameters could be identified synchronously. NSGA3 algorithm was used for the curve fitting part. The test scheme and parameter identification method were verified by the test result of a dynamic simulation test prototype. The transformation and test method proposed in this paper are not only applicable to the tests using other forms of signals, but also provide reference for other standstill tests.
