Abstract

The invention discloses a fault locating method and device for an intelligent substation, wherein the method comprises the following steps of: establishing a network topology corresponding to the intelligent substation, wherein the network topology comprises the association relationships among all secondary equipment in the intelligent substation; monitoring the operation state of the intelligent substation so as to obtain state information; and, in a condition that alarm information is generated in the intelligent substation, determining fault equipment triggering alarm information in the intelligent substation by utilizing the network topology and the state information. By means of the fault locating method and device disclosed by the invention, the technical problem that a fault cannot be located in time in the intelligent substation can be solved.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a fault location method and device for an intelligent substation. Background technique [0002] In the smart substation, the optical fiber communication network replaces the traditional secondary wiring. Through the network message, the measured values ​​of voltage and current, switch position, trip signal and other state quantities as well as SOE and action are transmitted between the secondary equipment. events and other information. [0003] The secondary system of the smart substation is divided into process layer, interval layer and station control layer, and high-speed Ethernet communication is used inside and between layers. The communication network of the whole system is divided into: the process layer communication network between the process layer and the interval layer, and the station control layer communication network between the interval layer and the station control...
