Embodiment Construction

[0032] Below in conjunction with accompanying drawing, technical scheme of the invention is further described:

[0033] like figure 1 As shown, the present invention provides a low-voltage distribution station electrical network topology identification system. The circle in the figure represents a 10KV transformer, the three horizontal lines represent a busbar, and the figure below the busbar represents a user-side 380V transformer. The electrical network topology identification system of the low-voltage distribution station area provided by the present invention uses multi-frequency MFSK pulse modulation communication and 470MHz wireless communication fusion technology, and various terminals transmit their own unique identification codes to the communication concentrator through low-voltage power line pulses, and can be used by 470MHz wireless communication is used as a backup communication method; the communication concentrator is responsible for managing and analyzing the r...

Abstract

The invention discloses a system for topology identification of electrical networks of a low-voltage distribution area. The system comprises a first communication unit embedded into a communication concentrator, a second communication unit embedded into a collector, a third communication unit embedded into an intelligent electric meter and a fourth communication unit embedded into an energy efficiency monitoring terminal, wherein the second communication unit is respectively connected to the first communication unit, the fourth communication unit and the third communication unit through a transmission module; and the transmission module comprises a low-voltage power line pulse modulation module and a 470 MHz wireless signal transmission module. Through utilization of a multi-network integration technology, the electric topology identification of supply networks is realized without changing a hardware structure, bidirectional quasi real-time communication between a power supply end and a power point can be realized, the first communication unit periodically and automatically analyzes a connection relation of the electrical networks of the area, the system can be integrated with an area electricity information acquisition device and complete electric topology data acquisition and uploading independently, and furthermore, the system has the characteristics of convenience for installation and high safety.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a system and method for identifying the electrical network topology of a low-voltage distribution station area. Background technique [0002] The automatic identification of the electrical network topology relationship in the distribution station is essentially to reliably obtain the connection relationship between the electrical equipment in the park, the community, and the building and its power supply, and store these connection relationships in a certain way. The power grid company is vigorously carrying out the work of connecting operation and distribution information. The electrical network topology of the distribution station area is very important for the power company to improve the management level of power supply reliability and improve the power supply service capability. Due to the large number of power distribution stations and complex electrical wiring, the...
