Abstract

The invention relates to a renewable energy monitoring information collection method based on a dispatching data network, comprising the following steps: (1) Acquiring collection terminal data; (2) Data push and storage; (3) Data encryption and uploading; (4) Monitoring information Unified reception; (5) Monitoring information assembly and transmission into the dispatching network. Compared with the existing technology, it solves the defect that the monitoring information of wind power, photovoltaic and other distributed renewable energy cannot be collected in real time due to the geographical environment and the lack of power optical fiber communication conditions, etc., and can effectively improve the monitoring and monitoring of renewable energy power plants. Management level, so as to better respond to national policies, and provide a data basis for the priority dispatch of renewable energy power plants in the power system.

Description

technical field [0001] The invention relates to the technical field of power systems and automation thereof, in particular to a method for real-time collection of renewable energy monitoring information based on a dispatch data network. Background technique [0002] Renewable energy is dominated by solar energy, wind energy, biomass energy and small hydropower, and people are paying more and more attention to it because of its clean, pollution-free and renewable resources. The development and utilization of renewable energy on the demand side and the construction of a sustainable energy supply system based on Internet information technology and complementing the power supply of the large power grid will become an inevitable trend in the development of smart grids in the future. [0003] At present, the widespread problems of distributed energy power generation projects mainly include the following aspects: the power generation equipment is scattered and not centralized, the ...
