Abstract

The invention relates to a data transmission system and method used between energy storage power station site equipment. The data transmission system is a distributed control system based on a PROFINET bus. The distributed control system comprises two or more sub units of the energy storage power station, an ethernet network ring framework is formed between the sub units of the energy storage power station through a PROFINET ethernet switch, and the PROFINET ethernet switch is connected with a monitor station of the energy storage power station. Each sub unit comprises a master station and two or more slave stations, and the master station is connected with the slave stations through the PROFINET bus. According to the technical scheme of the data transmission system and method used between energy storage power station site equipment, fast, synchronized and reliable data transmission can be realized.

Description

technical field [0001] The invention relates to a transmission system and a transmission method of an energy storage power station, in particular to a data transmission system and a method used for field devices of an energy storage power station. Background technique [0002] With the development of renewable energy such as photovoltaic / wind power generation, energy storage power stations can improve the ability of photovoltaic / wind power generation to connect to the grid, and the application of energy storage power stations will gradually increase; Standard for the realization of integrated and consistent automation solutions based on Industrial Ethernet; PROFINET supports the integration of distributed field devices and time-critical applications that communicate with Ethernet, as well as the integration of component-based distributed automation systems; at the same time, As an open real-time industrial Ethernet communication protocol, PROFINET realizes the control of mul...
