Abstract

The embodiment of the invention provides a communication control system for a photovoltaic field station, method and device. The device comprises a receiving module and a transmitting module, whereinthe receiving module is used for receiving a first control command of a field station quick control subsystem and/or periodically acquiring photovoltaic operation data of a photovoltaic controller; and the transmitting module is used for transmitting the received first control command to the photovoltaic controller and/or transmitting the acquired photovoltaic operation data to the field station quick control subsystem. A direct communication control link is built between the field station quick control subsystem and the photovoltaic controller, the communication level between the field station quick control subsystem and the photovoltaic controller is reduced, the response speed of photovoltaic power station control equipment is improved, the control period is shortened, and good technical effects of optimizing a communication mechanism are acquired.

Description

technical field [0001] This application relates to the technical field of wind power generation, in particular to a communication control system, method and device for a photovoltaic field station. Background technique [0002] As clean and renewable energy, wind energy and solar energy play a positive role in increasing my country's energy supply, adjusting energy structure and protecting the ecological environment. [0003] With the increasing penetration rate of new energy generating units, the centralized connection of large-scale photovoltaic power plants has brought new challenges to the safe, stable and efficient operation of the power system. [0004] In the actual operation of the power grid, when the power consumption does not match the power supply, it will cause a small change in the power grid frequency and a small component with a short period of change. Usually, the fluctuation of the power grid frequency can be corrected by the self-frequency of the generator...
