Embodiment Construction

[0022] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0023] like figure 1 , 2 As shown, the method for collecting renewable energy monitoring information based on the dispatching data network of the present invention includes the following steps:

[0024] (1) Acquisition of terminal data: based on MODBUS, OPC and other communication protocols, periodically read all monitoring information of renewable energy power plants (including working condition data, power data, environmental data, etc.) from remote measurement and control terminals through RS485 bus connection. , where the reading cycle is 1 second.

[0025] (2) Data push and storage: build a centralized collection and storage module on the side of the renewable energy power plant, and push the terminal data obtained in (1) to th...

Abstract

The invention relates to a renewable energy monitoring information acquisition method based on a scheduling data network. The method comprises the following steps that (1) the terminal data are acquired; (2) data pushing and storage are performed; (3) data encryption and uploading are performed; (4) monitoring information unified receiving is performed; and (5) the monitoring information is assembled and transmitted to the scheduling network. Compared with the methods in the prior art, the defect that the monitoring information of wind power, photovoltaic and other distributed renewable energycannot be collected in real time because of the problems of the geographical environment and no electric power optical fiber communication condition can be solved, the monitoring and management levelof the renewable energy power plant can be effectively enhanced, the national policy can be better responded and the data basis can be provided for priority scheduling of the renewable energy power plant in the electric 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 dispatching 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,...
