A distribution network automation terminal detection method and system

Abstract

The invention discloses a system and a method for detecting a distribution network automatic terminal. The system comprises a program control power supply, a standard meter and a detection device, wherein the program control power supply is used for supplying power and providing a test signal which comprises test voltage and test current to a detected terminal according to a signal command which is externally input; the standard meter is used for displaying the test signal which is generated by the program control power supply; and the detection device is used for sending the signal command to the program control power supply or the detected terminal, generating a detection result in response to the signal command according to the detected terminal, and storing the detection result. Functions, the accuracy and a communication protocol of the distribution network automatic terminal can be integrally detected. The invention is widely applicable to establishment of a distribution network automatic system, the performance and functions of the distribution network automatic terminal can be standardized, product quality is improved, the potential safety hazard of the distribution network automatic system can be effectively reduced, the level of safe and stable operation of a power distribution network is improved, the reliability of a power distribution system is improved, and solid foundation is laid for promotion of the establishment and application of a power distribution automatic system.

Description

technical field [0001] The invention relates to the field of detection of power terminals in distribution networks, in particular to a detection method and system for distribution network automation terminals. Background technique [0002] In recent years, with the continuous deepening of the transformation of urban and rural power grids, the power supply reliability and power supply indicators of the distribution network have been greatly improved. Many units have carried out pilot work on power distribution automation at different levels and scales, and accumulated a lot of experience. Great progress has been made, such as: the distribution automation system has gradually transitioned from the timing setting and cooperation of the recloser to the fault detection through the feeder automation terminal, fault isolation and non-fault area restoration of power supply; the cost performance of key equipment for domestic distribution automation Significantly improve and gradually...

AI Technical Summary

Problems solved by technology

[0006] 1. The existing distribution network automation terminal detection platform is only for the distribution transformer remote terminal TTU, which cannot fully cover all remote terminals in the distribution network automation system, which is not conducive to the overall development of the distribution network automation system construction;

[0007] 2. The existing distribution network automation terminal detection platform only realizes the detection of some functions of the remote terminal TTU of the distribution transformer, and the detection items are not comprehensive;

[0008] 3. When the existing distribution network automation terminal detection platform conducts event tests (such as voltage over-limit tests) on the remote terminal TTU of distribution transformers, it uses computer instructions to simulate instead of real voltage and current. Correctly simulate the operating conditions of the power grid, so the detection conclusion is unreasonable
