The invention discloses a monitoring method for electric energy quality of a distributed power generation system. The monitoring method comprises the steps of: receiving electric energy quality data of a corresponding power generation system sent from an electric energy quality monitoring apparatus; preprocessing the electric energy quality data to obtain electric energy quality steady state data and electric energy quality transient state data; and displaying the electric energy quality steady state data and the electric energy quality transient state data. The method can monitor the electric energy quality of each power generation system in the distributed power generation system and can display the electric energy quality data for users to check conveniently. The invention also discloses a monitoring system for electric energy quality of the distributed power generation system
Description
technical field [0001] The invention relates to the electrical field, in particular to a method and system for monitoring power quality of a distributed power generation system. Background technique [0002] The current global power supply system is a centralized single power supply system characterized by large units, large power grids, and high voltage. Although 90% of the world's power loads are supplied by this centralized single large power grid, today's society has higher and higher requirements for the quality, safety and reliability of energy and power supply. Require. Disturbances caused by faults at any point in the large power grid will have a greater impact on the entire power grid, and in severe cases may cause large-scale power outages or even the collapse of the entire network, resulting in catastrophic consequences. [0003] The combination of large power grid system and distributed power generation system is the main method to save investment, reduce energ...
