Problems solved by technology

With the increasingly complex distribution network construction, load transfer is very common, but the current system only limits the load current after the transfer, and cannot analyze the actual voltage impact, and lacks effective preventive measures for high and low voltage risks
It is also impossible to evaluate the countermeasures for high and low voltages generated during distribution network operation

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to an analysis and optimization method and system based on causes of distribution network voltage quality. Background technique [0002] At present, the power grid has been equipped with multiple business systems such as production system, metering automation system, and dispatching automation system. In the actual operation process, the current professional systems cannot automatically collect and compare data for distribution network work management, requiring a lot of manual maintenance. Dispatching professionals do not have distribution network equipment operation records and account information for safety research on distribution network load transfer methods, and lack targeted preventive measures for possible distribution network low voltage problems. With the increasingly complex distribution network construction, load transfer is very common, but the curre...
