Control method of photovoltaic power station

Abstract

The invention discloses an ultra-large capacity top-speed intelligent control method of a photovoltaic power station, comprising the following steps of: (1) building an operational model of the photovoltaic power station, and defining a data set containing a plant station, an equipment group, equipment and a control point; (2) pre-configuring the information of the photovoltaic power station; (3) reading an information configuration file; (4) selecting and configuring an object; (5) intelligently sending a control command; (6) carrying out the statistics, the analysis, the storage and the display of operation; and (7) releasing a control authority. In the invention, the ultra-large capacity top-speed intelligent control method of the photovoltaic power station is provided, a large amount of control point information of the photovoltaic power station is stored to a control platform by utilizing an operational model from control point modeling to control point selection to control point intelligent control, and operators can fast execute control operation by only simply selecting and configuring, thereby reducing the workload of maintenance personnel for the operation of the photovoltaic power station, increasing the work efficiency, also lowering the occurrence rate of misoperation and ensuring the normal operation of the photovoltaic power station.

Description

technical field [0001] The invention relates to the technical field of green energy power generation, in particular to a control method for a photovoltaic power station. Background technique [0002] As the energy crisis is approaching, new energy has become one of the main energy sources in the world in the future.

[0002] As the energy crisis is approaching, new energy has become one of the main energy sources in the world in the future. Photovoltaic power generation, as an emerging green energy industry, has gradually received national attention and support. Compared with other methods, the power conversion efficiency is low, and the power generation is greatly affected by weather factors. In the prior art, in order to meet the requirements of a certain power generation target, a large-scale paving of solar panels and inverters in photovoltaic power stations is adopted. and other power generation equipment to make up for the above-mentioned defects of the photovoltaic power station. Generally, in a photovoltaic power station with a power generation capacity of 40MW, there are usually thousands or even tens of thousands of control points ( Including remote control and remote adjustment), due to the large number and types of equipment in photovoltaic power plants, the control points of equipment, and the types of control operations, at present, there is no control method for photovoltaic power plants that is flexible in configuration, efficient in operation, and powerful in function. Auxiliary power station operation and maintenance personnel to complete daily operation, equipment maintenance and other work, power station operation and maintenance personnel to perform various operations, heavy workload, low work efficiency, high incidence of misoperation, affecting the normal work of photovoltaic power plants
