Disturbance and Detection Method Based Power Quality

Due to the increasing diversification of power sources and power loads, power quality disturbance signals in power systems have become increasingly complex and diverse. At the same time, a large number of high-precision and high-sensitivity electrical equipment have continuously improved the power quality requirements for power supply. This poses a huge challenge to the governance of power quality. The premise of power quality management is to correctly detect and identify these disturbance signals. This paper studies the power quality detection methods, and summarizes several commonly used power quality disturbance detection methods and identification methods, which lays a foundation for the further study of power quality disturbance problems.
