摘要

提出了一种基于泵变频电驱动过程能量过程监测的电液复合机电系统非定常模式诊断方法。它是基于对瞬时功率导数及其在能量通道所有元素上的幅频特性的分析。确定了识别应急模式的诊断标志，并制定了一套组织和技术措施，利用管网中的水动力和空化保护装置、主动吸能器和减少动负荷装置，防止非定常模式的发展。

The Energy Method for the Diagnosis of the Emergency Modes of Electrohydraulic Complex Electromechanical Systems

A method for diagnosing unsteady modes of electrohydraulic complex electromechanical systems based on monitoring of energy processes as part of the variable-frequency electric drive of the pump has been developed. It is based on the analysis of instantaneous power derivatives and its amplitude-frequency characteristics at all elements of the energy channel. Diagnostic signs of the identification of emergency modes have been determined and a set of organizational and technical measures has been formulated to prevent the development of an unsteady mode by using hydrodynamic and cavitation protection devices, active energy absorbers and devices for reducing dynamic loads in pipeline networks.
