Monitoring method and system of battery energy storage station

Abstract

The invention discloses a monitoring method and system of a battery energy storage station and relates to monitoring and control methods and systems of the battery energy storage station. The method includes the steps of firstly, a special embedded control mainframe is configured into in the monitoring system of the battery energy storage station, the embedded control mainframe connects the batter management system and the power conversion system of the battery energy storage station to form a process level network, and the monitoring system network of the battery energy storage station is divided into a control network and a monitoring network which are mutually independent; secondly, during monitoring of the battery energy storage station, the monitoring information of the battery management system and the power conversion system are transmitted to a monitoring center through the monitoring network; the control information of the battery management system and the power conversion system are accessed to the control mainframe through the control network, and the control mainframe transmits the control information to the monitoring center; the state information monitoring and control can be fast transmitted to the battery management system and the power conversion system through the two independent networks respectively. The invention further discloses a monitoring system using the method. The monitoring method and system has the advantages that the reliability and response speed of the monitoring system of the battery energy storage station are increased greatly during application, and the operation performance of the battery energy storage station is increased at the same time.

Description

technical field [0001] The invention relates to a monitoring method and a monitoring system of a battery energy storage station. The invention belongs to the technical field of monitoring and control equipment of a battery energy storage station in a power system. Background technique [0002] Energy storage technology refers to a technology that converts electrical energy into other energy that is easy to store through a certain device and stores it efficiently. When needed, the stored energy is conveniently converted into the required energy. As a new type of electrochemical energy storage technology, battery energy storage technology has attracted more and more attention from the industry due to its advantages such as good environmental adaptability, high energy density, small footprint, high efficiency, and short construction period. [0003] As the central nerve of the battery energy storage station, the battery energy storage station monitoring system is an important ...
