A Method for Rapid Diagnosis of Topological Faults in Grid Model Based on dts Virtual Switch

Abstract

The invention discloses a method for rapidly diagnosing topology fault of a power network model based on a DTS virtual switch, which comprises the following steps: 1) configuring a line model and designing a virtual switch; 2) when that fault occur, firstly, the fault range is checked; 3) if in that dispatch scope of other companies, switch to the DTS virtual switch circuit diagram, pull on the virtual switch, and determine whether the fault point is within the control scope of the virtual switch, if so, notify the corresponding dispatch department to remove the fault; 4) if that fault point is not in the control range of the virtual switch, repeat the step 3) until the fault point is found; 5) if in that dispatch scope of the company, open the line diagram of the plant and station withinthe dispatch scope, switch to the DTS application, then through one by one manual setting, judge the fault point, find out the fault reason, and notify the relevant department for maintenance after finishing the inspection. The invention can quickly diagnose the topology fault of the model, and reduce the accidents of voltage regulation failure and distribution network self-healing failure.

Description

technical field [0001] The invention relates to a grid topology fault diagnosis method, in particular to a method for rapidly diagnosing grid model topology faults based on a DTS virtual switch. Background technique [0002] Grid model topology is an important part of power system dispatching control. In the work of power dispatching control, whether the grid model topology in the power monitoring system is correct or not is related to the reliability and safety of the entire power grid. DTS is a power dispatching training simulation system. Its data can be obtained in real time from the power data acquisition network, but it cannot control the primary equipment in the substation in real time. It is suitable for diagnosing the power grid model topology without any impact on the actual operation of the power grid. [0003] The topological relationship of the power grid model supports various business functions such as AVC, PAS, state estimation, and power flow calculation on ...

Problems solved by technology

[0005] In the power monitoring system, applications such as SCADA and FES in Zone I are responsible for real-time monitoring and data analysis. The model topology under these applications should follow the principle of consistency with the primary equipment. If the model topology is different from the equipment in the substation, It will cause misoperation when the dispatch control center operates the equipment in the station or issues orders for the operation in the station
