Embodiment 1

[0053] Such as figure 2 Shown is a schematic diagram of a pumped storage unit failure prediction and health management system proposed in Embodiment 1 of the present invention,

[0054] It consists of three levels: equipment monitoring layer (subsystem level), processing center layer (module level), and decision support layer (system level); they are described below.

[0055] Bottom layer: equipment monitoring layer (subsystem level);

[0056] In each subsystem of the pumped storage unit (pump turbine system, generator motor system, vibration swing system, governor system, water inlet valve system, compressed air system, transformer system, static frequency converter system, excitation, GIS and GCB system , other systems) arrange in-machine self-inspection equipment to monitor the real-time operating status of each subsystem.

[0057] Middle layer: processing center layer (module level);

[0058] Construct the data acquisition module, data processing module, state evaluati...

Abstract

The invention discloses a system and method for failure predication and health management of a pump storage unit. The system for failure predication and health management of the pump storage unit comprises an equipment monitoring module, a processing center module and a decision support module; implementing of the method comprises the steps that a state monitoring sensor and built-in self-checking equipment are utilized to monitor the operating states of sub systems of the pump storage unit in real time, and state characteristic data of the sub system of the pump storage unit are obtained; the state characteristic data of the sub systems are processed and analyzed, and a maintenance decision suggestion of the pump storage unit is obtained; and by utilizing the maintenance decision suggestion of the pump storage unit, and through comprehensive analysis, failure predication and health management of the pump storage unit are achieved. According to the system and method for failure predication and health management of the pump storage unit, the system is perfect and reasonable, the method is effective and practicable, the system and the method can be used for implementing preventative state maintenance on the pump storage unit, and the overall operation level of the pump storage unit is enhanced.

Description

technical field [0001] The invention belongs to the field of health management of hydraulic power generation units in electric power systems, and more particularly relates to a system and method for fault prediction and health management of pumped storage units. Background technique [0002] With the rapid development of economy and society, the power load increases rapidly, and the peak-to-valley difference continues to increase. The grid has higher requirements for stability, and the insufficient peak-shaving capacity will become a key problem restricting the development of the power system. As a world-recognized flexible and reliable peak-shaving power source, the pumped-storage power station, with its unique operating characteristics of peak-shaving and valley-filling, plays the role of regulating load, promoting energy saving of the power system and maintaining the safe and stable operation of the power system, and has gradually become an effective power system. an indi...
