Abstract

The invention discloses power line carrier communication modules with power grid topology sensing function. The modules comprise a voltage dual channel phase detecting unit, a characteristic quantitypulse current transmitting unit, a characteristic current signal detecting unit, a dual mode communication unit, and a central processing unit, wherein the power line carrier communication module of asensing node and the power line carrier communication module of a sensed node establish a data and command interaction by using a dual mode communication mode, the voltage dual channel phase detecting unit generates a phase synchronization signal, the characteristic quantity pulse current transmitting unit of the sensing node generates and transmits a characteristic quantity pulse current signalof measuring the topology, the sensed node detects the weak pulse current signal in the power grid line network and transmits the signal to the central processing unit, and the central processing unitestablishes the topology of the power grid through data calculation. The invention realizes the automatic physical topology identification of the power grid.

Description

technical field [0001] The invention belongs to the technical field of electricity consumption information collection, and in particular relates to a power line carrier communication module with a grid topology sensing function. Background technique [0002] For a long time, power supply companies have mainly determined the location of low-voltage distribution network faults based on customer calls. Before the deployment of smart meters, the outage management system was mainly relied on for low-voltage network fault handling. Predict the position of the drop insurance or switch according to the calls made by the user after a power outage, analyze the scale of the power outage, personnel strength, and emergency repair plan, determine the priority of emergency repair, calculate the required work force on site, estimate the recovery time, and manage the site Work. The power outage management system is a subsystem of the distribution network management system. The control room...
