Distributed multi-power supply airport intelligent microgrid system

Abstract

The invention discloses a distributed multi-power supply airport intelligent microgrid system, which comprises a distributed multi-power-supply module, an intelligent control module and a centralizedcontrol background, the distributed multi-power-supply module comprises a solar energy power supply sub-module, a wind power supply sub-module, a mobile energy storage power supply sub-module, a fixedenergy storage power supply sub-module, a local power grid power supply sub-module, a water conservancy power supply sub-module, a garbage power generation power supply sub-module and a diesel generator power supply sub-module. The intelligent control module comprises a solar power supply control sub-module, a wind power supply control sub-module, a mobile energy storage power supply control sub-module, a fixed energy storage power supply control sub-module, a local power grid power supply control sub-module, a water conservancy power supply control sub-module, a garbage power generation power supply control sub-module and a diesel generator power supply control sub-module. According to the invention, airport power quality can be effectively improved, electric energy is integrated and fully utilized, power supply pressure during peak hours of power utilization is relieved, reliability and safety of a power supply system are improved, and effective management of the airport power supply system is realized.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to an airport intelligent micro-grid system powered by distributed multi-power sources. Background technique [0002] At present, the airport power supply system generally adopts 1 or 2 AC 35kV or AC 10kV power sources from the local power department, and supplies the airport power distribution network after stepping down. After the line power failure, the electrical equipment can work normally. Diesel generators have been widely used as backup power sources, but they have disadvantages such as long start-up time (the whole process takes 5-30s), poor power supply quality (large voltage and frequency fluctuations), and easy detection. The mobile energy storage power vehicle (similar to Dayi battery) has the advantages of flexible use and fast start-up power supply, but its limited energy storage cannot provide power for aircraft, lights, etc. for a long time, so it ca...

Problems solved by technology

Diesel generators have been widely used as backup power sources, but they have disadvantages such as long start-up time (the whole process takes 5-30s), poor power supply quality (large fluctuations in voltage and frequency), and easy detection

The mobile energy storage power vehicle (similar to the Dayi battery) has the advantages of flexible use and fast start-up power supply, but its energy storage is limited and cannot supply power to aircraft, lights, etc. for a long time, so the effective and safe operation of the airport cannot be guaranteed
