Automatic numbering system for localized distributed protection management host and numbering method thereof

Abstract

An automatic numbering system for a localized distributed protection management host involves the field of a localized distributed protection management host. At present, localized distributed protection management is not in place. The localized distributed protection management host provided by the invention is connected with a remote localized protection control device, the localized distributedprotection management host includes distributed N sub-machines that are connected through a ring network, the remote localized protection control device is connected with the sub-machine as the localized distributed protection management host, the sub-machines are connected one by one in order according to the characteristics of the ring network to realize the initialization setting work of the device parameters and numbers, and the initialization result is fed back to the localized distributed protection management host through the Nth sub-machine to judge whether the initialization is completed, so as to realize the initialization work of each distributed sub-machine. The technical solution is capable of conveniently performing related initialization work on the connected sub-machines through the remote localized protection control device.

Description

technical field [0001] The invention relates to the field of in-situ distributed protection management hosts, in particular to an automatic numbering system and a numbering method for in-situ distributed protection management hosts. Background technique [0002] When the power grid fails, the relay protection device can quickly remove the faulty equipment, which plays a very important role in ensuring the safe and stable operation of the power grid, and is an important part of the power system. The distributed scheme for busbar transformer and other cross-interval protection is in line with the development trend of decentralized layout and localization of substation protection, and the distributed protection adopts the method of decentralized data collection and centralized processing, which is compared with the centralized busbar protection with centralized collection and centralized processing. method has great advantages. The sub-machines of the distributed protection wo...

Problems solved by technology

Since the display screen cannot display normally in a low-temperature environment, and the protection level of the display screen cannot meet the overall protection level requirements of the local protection device, the local protection device does not have a display device, so the parameters of the local protection device cannot be set. Check the working conditions of setting and operation, and the distributed protection is externally reflected as a protection device. Only one of the sub-machines is selected as the management host to connect with the remote operation of the local protection device, but each component sub-machine has no direct network connection and cannot Set the equipment parameters and numbers of each sub-machine through the remote local protection control device
