Coordinated control system and method for wind-solar hybrid power generation

Abstract

The invention provides coordinated control system and method for wind-solar hybrid power generation. The system comprises a system master station and a system slave station. The system master station is in communication connection with the system slave station through an industrial Ethernet. The system is in a distributed structure, the system master station is connected with the system slave station through the industrial Ethernet, and accordingly fast transmission of mass data is achieved. Information interaction with a monitoring center is achieved by GPRS (general packet radio service) or CDMA (code division multiple access) wireless communication, so that the problems such that wire communication of remote base stations under the limitation of geographical environments of islands, deserts and the like fails, or signal jamming possibly caused by long-range communication line connection can be avoided. Development is focused on effective recharge and discharge and normal operation in storage batteries, so that reliable power supply is guaranteed for remote communication base stations, and the service lives of the storage batteries are prolonged.

Description

technical field [0001] The invention belongs to the field of electric power automation, and in particular relates to a coordinated control system and method for wind-solar complementary power generation. Background technique [0002] Due to the continuous improvement of our country's national living standards, the penetration rate of mobile phones is getting higher and higher, and the coverage of mobile signals is also becoming wider and wider. The construction of communication base stations has gradually shifted from urban areas and villages to remote islands, mountains, and deserts. Coverage, these remote communication base stations cannot be connected to the mains due to the constraints of the geographical environment. The wind-solar hybrid power station composed of wind power generation technology and photovoltaic power generation technology can provide part or all of the electric energy for remote communication base stations, so as to make up for the insufficient power ...
