Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a high-voltage constant-frequency voltage-regulating and stabilizing power supply system equipped with an intelligent control system. Background technique [0002] With the rapid development of my country's economy, ship transportation has become one of the main modes of transportation for our country. The power load of ships is also increasing, and the air pollutants emitted by auxiliary machines after berthing are also increasing. , Air pollution control cannot be ignored. The Ministry of Communications and the Ministry of Environmental Protection have successively released the drafting documents of the "12th Five-Year Plan" for energy saving and emission reduction of road and waterway transportation and the "13th Five-Year Plan" for the reduction of major pollutants, and issued relevant shore power supply technical documents and construction technical specifications, et...

AI Technical Summary

Problems solved by technology

The existing shore power supply can only complete the voltage regulation by means of communication with the on-board grid-connected equipment. If it is separated from the on-board grid-connected equipment, it cannot automatically adjust the voltage. Sudden loading and unloading, excessive power consumption on board, will cause output voltage Unstable and low, causing harm to shipboard electrical equipment
