Project Introduction

Location: China

Project Name: Windfarm SCADA System in China

Products Deployed: IES-2042FX-SS

Project Requirement

• Swift and dependable redundant ring network protections
• Endurance under tough environments
• Long distance networking

Solution

Lian-Yun Harbor windfarms have 50 wind turbines generating 100 million kilowatt-hours of electricity annually. The SCADA system is established for real-time status monitoring of the wind turbines. The system, equipped with ORing products and technologies, is divided into 4 rings – A, B, C, and D. 54 ORing IES-2042FX-SS Ethernet switches are used to implement 4 redundant rings (which are well-protected by O-Ring redundancy technology): Ring A (13 wind turbines + 1 control unit), Ring B (13 wind turbines + 1 control unit), Ring C (12 wind turbines + 1 control unit), and Ring D (12 wind turbines + 1 control unit).

Each wind turbine is accompanied by one ORing IES-2042FX-SS Ethernet switch, BeckHoff PLC (information collector), and Beckhoff IPC (data monitoring terminal). The control center has 4 IES-2042FX-SS Ethernet switches, which are connected to the 4 redundant rings. Besides, there are 2 IBM servers. One of the servers stores monitor information data from Ring A and Ring B, and the other server stores monitor information data from Ring C and Ring D.
