As the new-type power system accelerates its construction, independent energy storage power stations serve as critical regulation resources for grid frequency modulation and peak shaving. Their operational reliability directly impacts renewable energy integration and grid security. Shanghai MRDCom Co., Ltd., through its proprietary brand MRD, adheres to a full‑stack independent development path. Its self‑developed “dual‑100%” domestic industrial switches – featuring 100% domestically sourced core components, fully self‑developed whole‑unit solutions, and fully controllable protocol stacks – achieve deep‑level independence and security from supply chain to technology foundation. At a standalone energy storage project in Shanwei, Guangdong, the deployment of our industrial switches has built a highly reliable, low‑latency communication “highway” for the massive data exchange within the station.

I. Project Background

The automation system construction for the Lanzhou Petrochemical Yulin 800,000 t/a Ethane‑to‑Ethylene Project is a key practice carried out under this context. Faced with typical petrochemical scenarios featuring long process flows, numerous equipment units, and high demands for continuous production, the automation system undertakes critical tasks such as production control, data acquisition, equipment monitoring, and operation scheduling. More importantly, it serves as the fundamental basis for ensuring safe, stable, and continuous operation of the entire plant.
For a large‑scale ethane‑to‑ethylene project, a stable, efficient, and reliable industrial communication network must be established among the control layer, management layer, and field device layer to truly support the smooth operation of the entire automation system. Especially in petrochemical environments, where electromagnetic conditions are complex and continuous production requirements are stringent, any communication fluctuation can have cascading effects on system interlocking, production organization, and operational efficiency.
Therefore, the reliability, redundancy capability, environmental adaptability, and manageability of industrial network devices become a critical link in the construction of the automation system.

Addressing the core pain points of energy storage scenarios, MRD industrial switches provide comprehensive communication protection for the project – from hardware design to software protocols.
Robust Transmission in Strong Electromagnetic Environments:
In energy storage stations, the frequent switching of numerous power electronic devices generates intense electromagnetic pulses that can easily cause data packet loss or communication interruptions. MRD switches are strictly designed to industrial EMC standards and have passed the highest level of IEC 61000‑4 series tests, ensuring zero error packets and uninterrupted transmission even in harsh electromagnetic fields, providing a “transparent channel” for critical protection signals between the BMS and PCS. For customers, this translates into lower false alarm rates and more stable frequency response.
Millisecond‑Level Self‑Healing for Unattended Operation:
The project adopts a ring‑network redundancy architecture, leveraging MRD’s proprietary MRD‑Ring® protocol. When any node or link in the network experiences an unexpected interruption, the system automatically completes path switching within milliseconds, with zero service awareness. This feature perfectly matches the remote centralized monitoring and minimal‑staff operation model of energy storage stations, significantly reducing the risk of downtime caused by communication failures, and allowing customers to focus more on power trading and revenue optimization.
Wide Temperature and Wide Voltage for Extreme Outdoor Environments:
In South China, summer conditions are hot and humid, and temperatures inside outdoor energy storage containers can exceed 60°C. MRD switches support a wide operating temperature range from –40°C to +85°C, featuring a fanless, fully enclosed metal design with IP40 protection rating, and dual redundant power inputs. They readily handle voltage fluctuations and extreme climates, ensuring stable service throughout the equipment’s entire lifecycle. Customers experience significantly reduced equipment replacement frequency and lower overall O&M costs.
