PRS-7921 Energy Storage Local Control Terminal

Product Description

The PRS-7921 Energy storage local control terminal is an Ethernet-based intelligent logic unit introduced by CYG SUNRI using mature computer technology and network communication technology by summarizing years of experience in the development and operation of substation integrated automation systems. The purpose of this terminal is to satisfy the requirement of online monitoring of energy storage stations and the development of higher-level system monitoring.As a communication device of comprehensive automation system deployed in the substation, PRS-7921 follows the DL/T860 protocol, which is connected the BMS, PCS and the higher-level monitoring system in the station, and coordinates the data and command interaction between various devices and monitoring terminals. Specifically, it receives data sent by the online monitoring device in real time, aggregates, displays, processes, analyzes and stores the data, and realizes the control of energy storage device and standard communication with the higher-level system.

Scope Of Application

It is applicable to energy storage power stations of 100-megawatt, which is used in local monitoring and data analysis.

Technical Features/Advantages

It has a complete communication protocol library from top to bottom, which also supports various standard protocols of power industry, and has interoperability with the same protocols from different manufacturers;

It can improve self-inspection information and send it to the main station, record operation logs, and recover from abnormal conditions without losing the stored data;

Equipped with engineering configuration tools, it can support the remote maintenance of main station system using SSH, telnet and remote debugging tools;

Through the WEB or CS client, it provides a user-friendly graphical human-machine interface, with functions such as data configuration, browsing, debugging, and data export;

It can manage and configure the basic information of energy storage unit in the station, including device type, communication parameters, and fixed value, and it also supports real-time reception and forwarding of fixed value of energy storage unit issued from the main station system.
