Abstract

The embodiment of the invention provides an equipment self-resetting temperature determining method and device. The equipment self-resetting temperature determining method comprises the following steps: generating an equipment temperature rising curve according to the acquired temperature value in the equipment operation process and the corresponding acquisition time; determining the temperature change slopes corresponding to different acquiring time according to the temperature rising curve; determining the slowly rising temperature point according to the temperature change slopes; with the beginning point of the acquiring time corresponding to the slowly rising temperature point, and moving the set time length forwards to obtain the self-resetting time point; and determining the temperature corresponding to the self-resetting time point as the self-resetting temperature according to the temperature rising curve. Through the embodiment of the invention, the self-resetting temperaturecan be set properly, effective reset of a wind driven generator is realized, and loss of generating capacity is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of industrial control, in particular to a method and device for determining the self-reset temperature of equipment. Background technique [0002] Self-resetting is a technical means to allow programs, circuits, etc. to return to the initial state and restart operation. It is widely used in the field of industrial control to realize automatic recovery after equipment failure. [0003] Take the wind generator as an example. The wind generator is a device that realizes two energy conversion processes from wind energy to mechanical energy and from mechanical energy to electrical energy. The wind wheel system realizes the energy conversion from wind energy to mechanical energy, and the control system of the wind generator realizes The energy conversion process from mechanical energy to electrical energy. In order to ensure the normal operation of wind turbines, the control system needs...
