摘要： A position of a rotor of a synchronous generator is measured under no load and under load. An angle of difference between where a terminal voltage crosses a zero-point and the marked position of the rotor under no load is calculated. A load angle is of the synchronous generator based the no load angle of difference and the load angle of difference.
