The condition monitoring and diagnosis system of a 300MW pumped storage unit is introduced. The purpose of this system is to provide the basis and means for timely and pertinent maintenance of pumped storage units. The structure, operation characteristics and common faults of 300MW pumped storage unit are analyzed. On this basis, the hardware configuration and sensor arrangement of vibration monitoring and diagnosis system of pumped storage unit are introduced. Through the demand analysis, the functional structure module and data flow diagram are given. Finally, the introduction and summary of the implementation system are completed. The software system has been put into operation successfully based on the WINDOWS-NT network platform.
