Intelligent transformer station monitoring information step-by-step checking and accepting method based on three-layer double-network structure

Abstract

The invention discloses an intelligent transformer station monitoring information step-by-step checking and accepting method based on a three-layer double-network structure, and the method comprises the steps: building an in-station background information checking and accepting point table for a target intelligent transformer station; dividing the monitoring information checking and accepting operation of the intelligent transformer station into two stages based on the in-station background information checking and accepting point table: carrying out the local simulation of an actual signal and in-station background checking and accepting, and enabling a process layer network to apply a digital signal and carrying out the remote monitoring checking and accepting; guaranteeing the full-coverage checking and accepting of information transmission links through the overlapping of measurement and control devices at the monitoring information transmission links at the two stages. The method can reduce the total monitoring checking and accepting time, can complete the remote monitoring checking and accepting operation in seven days after the connection of a remote channel, greatly shortens the time from the connection of the remote channel and the moment when the transformation station meets a use condition, guarantees the use time node, is high in checking and accepting quality, is short in checking and accepting time, and saves the manpower resources.

Description

Technical field [0001] The invention belongs to the technical field of substations, and in particular relates to a step-by-step acceptance method for intelligent substation monitoring information based on a three-layer two-network structure, which is applied to new, renovated, and expanded intelligent substations. Background technique [0002] Smart substation is an important part of the smart grid. Its basic features are the digitization of the entire station information, the networking of communication platforms, and the standardization of information sharing. It automatically completes basic functions such as information collection, measurement, control, protection, measurement and monitoring, and can be based on needs It supports advanced functions such as real-time automatic control of the power grid, intelligent adjustment, online analysis and decision-making, and collaborative interaction. With the gradual advancement of the construction of smart substations, the correspon...

Problems solved by technology

The traditional monitoring information acceptance method generally uses the actual analog signal on the spot to monitor the remote acceptance after the telecontrol channel is opened. The quality is often difficult to be reliably guaranteed, which brings hidden dangers to the safe and stable operati...
