掌握母线电压状态信息是一项十分重要且需要长期坚持实施的工作。通过开展这项工作,可以了解、掌握整个电网的电压一负荷在不同时间段内的波动情况,掌握系统电压谐波分量的大小及变化情况,同时结合母线所带出线的负荷性质、时段特征等信息对各个整个电网运行情况进行深入了解。一旦系统内发生故障(包括大范围电压波动、谐振等异常运行情况),我们可以根据 Mastering bus voltage status information is a very important and long-term adherence to the implementation of the work. Through carrying out this work, we can understand and grasp the voltage-load fluctuation of the whole power grid in different time periods, understand the magnitude and change of harmonic voltage components of the system voltage, and at the same time combine the load characteristics of the outgoing wires of the busbar, the period characteristics and so on Information on the operation of the entire power grid in-depth understanding. Once the system fails (including a wide range of voltage fluctuations, resonance and other abnormal operation), we can according to
