For hydropower plants, the integrated E&M solution is a systematic approach integrating the mechanical power system, electrical control and protection system, and intelligent monitoring and scheduling system.
Precisely match high‑efficiency turbines with synchronous generators based on the specific head and flow characteristics of the power plant to achieve efficient conversion of mechanical energy into electrical energy. Meanwhile, integrate governors and excitation systems to ensure the stability of the speed, voltage, and frequency of the unit and realize the compliance with grid‑connection criteria.
Establish a control platform centered on industrial microcomputer, provide the platform with primary and secondary electrical systems, including the monitoring and protection system, DC power system, HV/LV systems, and communication system, and integrate key functions such as unit start/stop, load regulation, grid-connected/off-grid switching, and emergency shutdown in the platform. Connect to a sensor network to enable real-time acquisition and analysis of operational parameters and to support a three-tier operation mode, namely local control, remote automatic control, and centralized cluster scheduling.
Apply intelligent design for auxiliary systems like cooling, lubrication, and drainage so that they can operate in a coordinated manner with one another by means of electric valves, variable-frequency water pumps, and the central control system and realize on-demand start/stop operations. Provide emergency power supplies and backup equipment to ensure fault tolerance and operational resilience.
Integrate the condition monitoring module and the fault diagnosis module, and leverage AI algorithms to analyze equipment operational data for early warnings of faults such as wear, leakage, and overload. Build a digital O&M platform that links equipment registers, maintenance records, and spare parts inventory together to support remote O&M guidance and O&M process automation.
Incorporate the ecological flow release control module to coordinate sluice gates with real-time flow monitoring devices, ensuring downstream discharge meets ecological protection requirements. Integrate the safety system (comprising lightning protection and grounding, fire alarm, and leakage current protection) and ensure the safety of both personnel and equipment by means of electrical interlocks and mechanical protection devices. Stay in sync with the grid scheduling platform and the environment monitoring platform to achieve compliant data uploads.
