System Overview

A hydroelectric power station is a hydraulic device that converts water energy into electrical energy. It is composed of various hydraulic structures, as well as mechanical and electrical equipment such as power generation, substation, and power distribution, forming an organic complex that cooperates with each other and works in coordination. The use of a DCS distributed control system can effectively manage and control the operating data of a hydroelectric power station. By collecting control data in real time and completing calculations and analysis, it can generate alarm information for abnormal situations and conduct timely control and adjustments.

COME-STAR Solution

System requirement:

1) The equipment can work stably for a long time in harsh environments such as high temperature and high humidity on site;

2) It adopts optical fiber data transmission to meet the comprehensive networking needs of various types of terminals on site;

3) It adopts industrial-grade design solutions to meet the requirements of stable and reliable operation under strong electromagnetic interference;

4) The product adopts a low-power power supply solution to meet the power supply requirements of special scenarios.

Solution:

The design of the power station's electrical protection, system shaft system, plant DC, plant power, and the factory's complete excitation and water turbine speed control systems should be made around the characteristics of the DCS control system and small and medium-sized hydropower stations. Taking full advantage of the DCS's strong information collection and processing capabilities, reliable system, and friendly human-machine communication, COME-STAR adopts a ring network structure. The single ring composed of CISCOM7120 industrial Ethernet switches at each LCU is coupled with the ring of the monitoring center to form a multi-ring topology structure. The product meets the stable and reliable application requirements under industrial level 4 anti-interference. The network has real-time acquisition functions, scalability, high reliability, high bandwidth, high-quality network signal transmission, and redundant backup.
