specific Embodiment approach 1

[0012] Specific implementation mode one: The steps of the method of the present embodiment are as follows:

[0013] Step 1. Keep the original conventional RTU forwarding mode of forwarding ground adjustment in a 220KV substation unchanged, and set up a four-wire analog transition communication link between the comprehensive automatic remote control host and the ground adjustment front;

[0014] Step 2. On the main station side of the ground survey, establish a virtual factory station without a specific map library structure. It only receives and interprets the information of the comprehensive automatic remote control host forwarded by the 220KV substation through the transition link. After the comprehensive self-transformation The collection of telecontrol information is sequentially accessed at intervals and increased one by one. In this way, there are two sources of information that are not repeated for this 220KV plant station. One is that the original plant station receive...

Abstract

The invention provides an uninterrupted forwarding soft transition method, relates to an electric power system integrated automation reconstruction information transmission method, and solves problems of the requirement of large amount of secondary cables, difficult and time-consuming construction and unsafe hidden trouble on persons and equipment. The method is realized by adopting transition of the secondary cables to a temporary transition link and a virtual plant station. A transition communication link is adopted, and integrated automation information and RTU acquisition information are transmitted to local dispatching simultaneously by additional arrangement of the temporary transition link. After the end of integrated automation reconstruction, the temporary transition link can also be used as metering and other channels. The virtual plant station is adopted, one virtual plant station is established at a local dispatching EMS master station to receive telecontrol information after 220KV integrated automation reconstruction, and information after reconstruction is correlated to the virtual plant station so that information correlation is realized, which has no interference on local dispatching and provincial dispatching. Personal and equipment safety is powerfully guaranteed, the construction period is shortened and large amount of cables and funds are saved.

Description

technical field [0001] The invention relates to a method for transmission of integrated self-correction information of a power system, in particular to a soft transition method for uninterrupted forwarding. [0002] Background technique [0003] At present, in addition to the real-time transmission of the telecontrol information of the 220KV substation to the provincial and local surveys, the information of some important measuring points has to be forwarded by the provincial dispatch to the network dispatch in real time. very strict. Since the 220KV substation constitutes the main network frame of the power grid, the reliability of power supply is very important. It is not allowed to carry out comprehensive self-renovation construction after a long-term power outage. To extend the renovation period, usually more than 3 months. The Provincial Commission has clear document requirements for the transmission of telecontrol information during the comprehensive self-renovation...
