Hydropower DCS System

A hydroelectric power station is a hydraulic device that converts water energy into electric energy. It is composed of various hydraulic structures, as well as mechanical and electrical equipment such as power generation, power transformation and distribution, etc., which cooperate with each other and work cooperatively.The DCS distributed control system can effectively manage and control the operating data of the hydropower station. By collecting the control data in real time and completing the calculation and analysis, alarm information can be generated for abnormal situations, timely control and adjustment can be carried out.

MW Solution

System requirement

-The equipment can work stably for a long time in harsh environments such as high temperature and high humidity

-Optical fiber data transmission is adopted to meet the comprehensive networking requirements of various types of terminals on site

-Adopt industrial-grade design to meet the requirements of stable and reliable work under strong electromagnetic interference

-The product uses a low-power power supply solution to meet the power supply requirements in special scenarios

Maiwe solution

The design of electrical protection, system shafting, plant DC, plant power, and the manufacturer's complete excitation, water turbine speed control system, etc. of the power station should be based on the characteristics of the DCS control system. Taking full advantage of DCS information collection, strong processing capacity and reliable system, Maiwe adopts the ring network structure. Each LCU site uses MISCOM7120 industrial Ethernet switches to form a single ring coupled with the monitoring center ring to form a multi-ring topology.Maiwe products meet the requirements of stable and reliable applications under industrial level 4 immunity. The network has the characteristics of real-time acquisition function, scalability, high reliability, high bandwidth, high-quality network signal transmission and redundant backup.
