Fault diagnosis method and system for large phase modifier

Abstract

The invention discloses a fault diagnosis method and system for a large phase modifier. The diagnosis method comprises the steps of obtaining the temperature, vibration, noise and electric parameter information of a diagnosed large phase modifier and forming an input vector; inputting the input vector into a trained machine learning classification model, and obtaining the fault state of the diagnosed large phase modifier, wherein the machine learning classification model comprises a mapping relation between the input vector and the fault state after being trained, and the system comprises thesystem corresponding to the method. The problems that the large phase modifier is large in size and complex in structure and comprises multiple parts are solved, the temperature, vibration, noise, electric parameters and the like can be synthesized to diagnose and analyze the equipment information of the phase modifier, the method and system have the advantage that the diagnosing structure is accurate and comprehensive, and faults of the large phase modifier can be found in time so that corresponding measures can be adopted.

Description

technical field [0001] The invention relates to a motor fault diagnosis technology, in particular to a fault diagnosis method and system for a large-scale adjustable camera. Background technique [0002] The condenser is a synchronous motor that runs without load. By changing the magnitude of its excitation current, it can be controlled whether it absorbs reactive power from the system or outputs reactive power. When the system voltage is low, it operates with over-excitation and becomes a reactive power supply, which can provide reactive power to the system to increase the system voltage; Absorb reactive power and lower the system voltage. The condenser is generally installed in the hub substation. The advantage of using a power regulator for reactive power compensation is that it is very convenient to adjust the reactive power load. By changing the magnitude of the excitation current, the reactive power output can be adjusted smoothly and continuously; it can be adjusted...
