一种配电网电能质量控制方法
By employing a real-time monitoring and dynamic adjustment power quality control method, the problems of delayed state identification and coordination in power quality control in distribution networks have been solved. This enables rapid response and precise adjustment to issues such as voltage sags and harmonic pollution, thereby improving the operational stability of the distribution network and the safety of electrical equipment.

AI Technical Summary
Existing power quality control technologies for distribution networks suffer from issues such as delayed state identification, poor adaptability of control strategies, lack of system coordination, and absence of closed-loop feedback. These issues result in unsatisfactory power quality improvement effects, especially in distributed power generation and nonlinear load environments where efficient and reliable power quality control is difficult to achieve.
By monitoring the power quality parameters of target nodes in the distribution network in real time, and combining preset control targets and dynamically adjusted control strategies, compensation control commands are generated to drive the power quality regulation device to perform dynamic compensation regulation, forming a closed-loop control throughout the entire process and ensuring that all regulation devices work together.
It improves the response speed and adjustment accuracy of power quality issues, flexibly responds to complex operating conditions, reduces overcompensation or undercompensation, enhances the stability and reliability of power distribution network operation, and ensures the safe and efficient operation of electrical equipment.
