Microgrid Central Controller

The product can be applied to user-side energy storage power stations, independent microgrids, off-grid/grid-connected microgrids, AC-DC hybrid microgrids, microgrid training rooms, wind, PV, storage, and charging stations.

Product Overview

PRS-3201 microgrid central controller is used for coordinated control and protection of microgrids. In grid-connected and isolated island states, through effective coordinated control of various distributed generators (DG) including energy storage equipment and various loads, the stable and cost-effective operation of microgrids is maintained, and the efficient connection and utilization of various distributed generators can be realized. PRS-3201 can be used in AC microgrids, DC microgrids and AC-DC hybrid microgrids with voltage from 0.4 to 35kV. It has the advantages of fast adjustment speed, high precision and good tracking performance, and can realize sec-level follow-up delay. While meeting the requirements of planned charging and discharging and AGC adjustments, the system supports active balanced management of battery pack SOC to ensure the charging and discharging capability of the power station. It also has functions such as diagnosis, early warning and panoramic analysis, thus it can effectively ensure the service life and safety of high-value assets of energy storage systems.

Product advantages

  • 01

    Based on CYG ET’s mature shelf technology of protection control platform, the maturity and reliability of the platform have been fully verified by the operation of protection measurement and control devices in thousands of intelligent substations.
  • 02

    The plug-in hardware design and modular software design based on general bus backplane technology facilitate function expansion.
  • 03

    The control network is independent of the monitoring network. The control network employs the IEC-61850/GOOSE multicast communication protocol, enabling the msec-level real-time dynamic response control of microgrids.
  • 04

    The control network supports dual-network redundancy configuration to further improve reliability
  • 05

    The product allows for the connection of in-situ microgrid controllers and associated terminal devices that do not support the GOOSE protocol through a front-end communication management machine, providing a high degree of flexibility and compatibility.
  • 06

    IEC-61870-104 protocol is supported between the uplink and EMS master station, and the interoperability requirements are met.
  • 07

    A number of time synchronization modes are supported, such as IRIG-B, IEEE 1588V2, and SNTP time synchronization.
