Smart grid network unified phasing system

Abstract

The invention relates to a unified phasing system for a smart grid network, which includes a main server, several branch servers, a standard phasing base station, and several hand-held phasing terminals; Determine the A / B / C three phases, use the phase angle information collected by the standard phasing base station as the phasing standard, and unify the phase identification standard. The invention can directly obtain the measurement result of the switchgear only once, which is more accurate, convenient and fast than the traditional nuclear phase method. Ground induction type nuclear phase can be adopted for overhead lines. It avoids the potential safety hazards in the operation process of the contact initial phase angle check, and can realize the initial phase angle check in thunderstorm weather. It improves the work efficiency of the initial phase angle check. Without opening the high-voltage chamber of the ring network cabinet, perform the primary and secondary verification of the ring network cabinet and confirm the phase sequence of A / B / C in the high-voltage chamber of the ring network cabinet.

Description

technical field [0001] The invention relates to a smart grid network unified phasing system for grid identification, color marking and phase sequence calibration. Background technique [0002] The development of the smart grid network unified phasing system has gone through four generations so far, from local wired phasing, to local wireless phasing and then to remote wireless phasing, and smart grid network unified phasing system. [0003] 1. Local wired phasing [0004] The first generation: The phasing of domestic high-voltage power lines adopts a wired method, and there are many devices. At least 4 people are required to operate the phasing, 1 person is in command, 2 people wear insulating boots and gloves as phasing personnel, and 1 person is an instrument Record. [0005] The phasing work is carried out according to the order of the commander. The high-voltage operator fixes the high-voltage lead wire on the insulating rod, and the length is appropriate. When the hig...

Problems solved by technology

[0005] The phasing work is carried out according to the order of the commander. The high-voltage operator fixes the high-voltage lead wire on the insulating rod, and the length is appropriate. When the high-voltage wire is used to touch the high-voltage power point with the insulating rod, the movements are coordinated, and the two take care of each other to avoid mistakes and cause danger. , the problem with this method is that for high-voltage lines, especially for phase detection of high-voltage overhead lines, two devices are required to be in contact with two wires at the same time, and it is inconvenient to use the wired method, and it has certain risks

[0012] The fourth generation: the above wireless phasing instruments can only complete point-to-point phasing. With the continuous development of the power system, in order to adapt to the complexity of the future power line network, we plan to develop a unified phasing system for smart grid networks
