Automatic heavy-load equipment early warning implementation method based on decision tree

Abstract

The invention discloses an automatic heavy-load equipment early warning implementation method based on decision tree in automatic monitoring technical field, and provides the early warning decision of the heavy-load equipment; a decision tree is created in each time period of each monitoring group to realize the early warning of the heavy-load equipment, the operation experience and relevant history information are sufficiently utilized to figure out the early warning scheme for the current power grid; when the heavy-load equipment really occurs overload situation, an early warning signal is transmitted in advance, the out-of-limit time is given to the dispatching staff so that the dispatching staff can quickly judge the early warning locations, the early warning property and the severity, determine the affected area, also take correct measures to reduce the affected range, avoid accidents and reduce the possibly-caused load loss. The invention greatly improves the safety of the power supply equipment and also improves the automation degree of the automatic power dispatching system.

Description

technical field [0001] The invention relates to a method in the technical field of automatic monitoring, in particular to a method for realizing automatic early warning of heavy-duty equipment based on a decision tree. Background technique [0002] Pursuing the safety, stability and economy of power system operation has always been the main goal of system operation. With the deepening of my country's power system reform and the rapid development of power construction, some large-capacity units, long-distance transmission lines, and high-voltage and ultra-high-voltage power transmission and transformation equipment have been put into operation one after another, causing some important equipment, such as primary transformers, lines The operating conditions are getting worse and worse, and the higher load rate and even overload will become more and more frequent. The monitoring of the operating status of these important equipment puts forward higher requirements. It is required...

Problems solved by technology

This mode does not use historical load change information, but only considers the current load change situation, and has the following problems: 1) False alarm: In the period of time when the load changes rapidly, even if the load of some equipment reaches the set value, the Due to the changing load, it will fall back quickly, and false alarms will occur according to the set value; 2) The early warning is not timely: in the period of monotonous and rapid rise of the load, the fixed value is used to trigger the early warning, and there is not much time left for the dispatcher to process. If it is not timely, it will cause some automatic devices to operate, and the load will be lost. In serious cases, it may cause accidents and cause major economic losses.
