Abstract

The invention discloses a Scada and electric energy acquisition system data fusion-based on-line sensing monitoring method and system for electric energy balancing of a substation. The method comprises the following steps of periodically acquiring power grid model data from a Scada system to identify each metering point; periodically acquiring configuration information and electric energy data ofthe metering point from an electric energy acquisition system; fusing the power grid model data and the electric energy data so that the data of each metering point is maintained to be consistent; building a balancing model; substituting the data of each metering point to the balancing model, and calculating unbalance rate; and generating warning record for a balancing point with balancing rate exceeding a threshold. On-line monitoring on a real-time balancing state of each electric energy balancing point of the substation is achieved, and the balancing control capability of dispatching on electric energy of the substation is improved.

Description

technical field [0001] The invention relates to the technical field of power dispatching control application, in particular to an online sensing and monitoring method for substation electric energy balance based on data fusion of Scada and electric energy acquisition system, and also relates to a monitoring system based on the monitoring method. Background technique [0002] The simultaneous line loss system of the power grid company requires the realization of the goals of "horizontal to edge, vertical to the bottom", "full-source collection, automatic generation, whole-process recording, and all-round supervision". According to the requirements of line loss management in the same period, combined with the status quo of electric energy system management, upgrade the power company to actively promote the improvement of the quality of electric energy collection data, and promote the centralized management of power balance in substations. Substation power balance monitoring is...
