对称运行 meaning in Chinese

symmetrical operation

When a single phase fault happened , the fault current is too low to affect the symmetry of a given power system . according to the regulations , it is admissible to run with fault for 1 hour or 2
小电流接地系统发生单相接地之后，因为故障电流很小，不至于影响系统的对称运行，所以，按照规程，可以继续运行1 2小时。
In this paper , according to the equation of voltage vector of single - phase motor operating at symmetrical condition , author presents a new voltage - vector pwm method of variable frequency control for single - phase motor . in system , the voltage vector is used as a control parameter
本文根据单相电动机对称运行时的合成电压矢量方程，提出了以合成电压矢量为控制量的单相电动机电压矢量式pwm变频调速控制方法，并进行了计算机仿真及制作了单相变频器。
The control system with such method is simulated and a inverter is made for speed control of single - phase motor . the method presented in this paper offers such advantages as easy implementation , large range of frequency and rapid dynamic response . furthermore , using this method , the single - phase motor with symmetrical or dissymmetrical windings can operate symmetrically
本文提出的变频调速控制方法具有系统设计简单易实现，调速范围大，动态响应快等特点，而且在电机绕组对称和不对称两种情况下均可实现变频调速的对称运行。
