Abstract

The invention discloses an alarm method for a power grid system. The alarm method comprises the steps: obtaining operation security type data, operation economic type data, operation quality type data and operation environment-protection type data in operation data of the power grid system; calculating security type monitoring indexes, economic type monitoring indexes, quality type monitoring indexes and environment-protection type monitoring indexes of the power grid system; and comparing all the monitoring indexes with corresponding preset thresholds respectively, and for the monitoring indexes which exceed the corresponding thresholds, giving out corresponding alarm signals. In addition, the invention discloses an alarm device for the power grid system. The alarm signals can comprise a pre-warning signal and an alert signal. An index system for monitoring the power grid system by using an alarm mode is established, so the power grid system can be monitored completely and systematically in the aspects of security, economic performance, quality and environment protection. The alarm paths are clear, and false alarm and alarm failure cannot occur.

Description

technical field [0001] The invention relates to the technical field of grid operation, in particular to a grid system alarm method and a grid system alarm device. Background technique [0002] For a long time, operators have relied on the power grid operation information provided by EMS (Energy Management System, energy management system) for power grid dispatching and control. As the scale of the power system expands, the complexity of the power grid continues to increase, and the requirements for operation continue to increase. The original monitoring EMS system can no longer meet the operation requirements of the smart grid. Especially with the rapid development of technology in related fields such as communication technology, information integration, and environmental monitoring, various professional fields in the power grid system have also developed their own corresponding monitoring methods, but these monitoring methods are designed to meet certain professional needs....
