China's pumped storage power station construction is entering a fast track, with individual station capacities often reaching millions of kilowatts. This imposes extremely high reliability requirements on computer monitoring systems, where industrial switches play an indispensable role. MRD industrial switches have been successfully deployed in the computer monitoring system project of the Zhejiang Songyang Pumped Storage Power Station, providing core communication support for this key energy project.
I. Project Background

Industrial‑Grade Reliable Design:
To address the harsh environment of strong electromagnetic interference and wide temperature/humidity variations in pumped storage power stations, MRD switches feature wide‑temperature and wide‑voltage design, and have passed Level 4 EMC immunity certification, ensuring 7×24 stable operation.
Deep Adaptation to Power Business:
The adopted MRD switches support the proprietary MRD‑Ring® ring network redundancy protocol, with fault recovery time of less than 50 ms, meeting the stringent real‑time and reliability requirements of the monitoring system.
Intelligent Network Management Capability:
Support for advanced features such as VLAN, QoS, and port mirroring enables the assignment of dedicated channels for different service traffic, ensuring priority transmission of critical control commands and supporting intelligent station dispatch.

A rack‑mountable Layer 2 industrial switch equipped with the Changzheng Centauri software, featuring 28 ports with BYPASS functionality: 4 Gigabit/Fast Ethernet auto‑sensing SFP ports + 8 Gigabit/Fast Ethernet auto‑sensing Combo ports + 16 Gigabit electrical ports + 16 LC BYPASS optical switches. Powered by redundant dual‑input isolated power supplies (24‑240 VDC / 100‑240 VAC).
From critical equipment to core systems, the successful application of MRD industrial switches in the pumped storage sector demonstrates the technical expertise of a leading domestic enterprise in power monitoring communications. This practice is setting an industry benchmark and highlights the significant value of building an independently controllable technology system in energy infrastructure.
