摘要
同步发电机空载电势■的有关参数对电力系统的运行与控制都是非常重要的,但是,目前现场的监控装置想要得到■的相关参数仍然存在困难。文中提出一种基于转子位置传感器的同步发电机■波形的实时生成方法,依据该方法开发的装置能够输出频率和相位都与空载电势■一致而幅值恒定的正弦电压信号,从而使得现场的监控装置能够像测量发电机机端电压那样方便地测量空载电势■的有关参数。详细地介绍了这种方法的工作原理和实现技术。
The Eq phasor＇s parameters of synchronous machines are very significant tor operauon anu cotltrol of power systems. But up to now, it is difficult to get the parameters of an Eq phasor. In this paper, a novel method based on rotor position sensors for real-time generating synchronous machine Eq waveforms is proposed. A new kind of device based on the proposed method is developed which can generate a constant-amplitude sine voltage waveform with the same phase and frequency as the Eq phasor of the involved synchronous machine, With this new kind of device, other monitoring and control equipments in the same plant can get the parameters of the Eq phasor easily, just as getting the parameters of the terminal voltage. In this paper, the basic principle and the implementation of the proposed method are introduced in detail.
