System Overview

Substations are at the core of the entire power grid and are responsible for the power supply of the area where they are located. They are characterized by a large number of construction and wide geographical distribution, which directly affects the power safety of users. Therefore, effective safety management of substations is crucial. As one of the important technical means necessary for intelligent power grids and safe production, the substation auxiliary monitoring system provides an important guarantee for the safe and stable operation of the power grid. With the promotion of power grid operation modes such as intelligent substations, unmanned substations, and centralized monitoring of substation operations, the importance of substation auxiliary monitoring systems has become more prominent.

COME-STAR Solution

System Requirement:

1) System integration with a highly modular structure;

2) Support for standard protocols in the power industry;

3) Network redundancy function;

4) Anti-interference ability for electromagnetic environment.

Solution:

The overall solution provided by COME-STAR consists of a video surveillance system, access control management system, dynamic environment monitoring system, and intelligent inspection system. System data is aggregated through an Ethernet ring network and transmitted to the monitoring center for unified scheduling and monitoring. COME-STAR's private CS-Ring redundant ring network protocol can ensure that normal data transmission is restored within 20ms in the event of an abnormal communication link. At the same time, the aggregation layer switch meets the requirements of the State Grid for network security monitoring devices and has passed the IEC61850-3 certification to ensure stable and reliable data transmission in harsh environments.
