Problems solved by technology

[0005] The embodiment of the present invention provides a method and a telecontrol device for a telecontrol device to delay the response to the dispatching master station, which solves the problem of adopting a fixed delay method to respond to the dispatching master station based on the actual power grid operation experience to avoid errors in the initialization process. If the data exists, it needs to be modified synchronously according to the site conditions. The fixed delay is not conducive to on-site maintenance work. The experience value of the delay of the telecontrol device is not accurate, which may lead to misadjustment or miscontrol of the power grid, which will bring huge losses to the power grid.

Abstract

The invention discloses a method and system of delayed response of a dispatching master station of a telecontrol device. The method comprises the following steps: completing a first telecontrol start within a preset first telecontrol start time; sequentially establishing databases through communication with all measuring and control devices in preset sequence; making comparison between the measuring and control devices with the databases established through communication and measuring and control devices recorded in a forwarding table of the dispatching master station; responding the dispatching master station corresponding to the forwarding table if the databases are established through communication for all the measuring and control devices recorded in forwarding table. According to the method and the system, when a constant delay method is adopted for responding the dispatching master station to avoid generation of error data in an initialization process according to the actual operating experience of the power grid, the existing technical problem that huge loss is caused for a power grid due to misadjustment or mistaken control for the power grid possibly caused by the situations that the synchronous modification of constant delay is bad for on-site maintenance work according to site conditions, and the empirical value of delay of the telecontrol device is inaccurate is solved.

Description

technical field [0001] The invention relates to the field of integrated automation systems of substations, in particular to a method and system for dispatching a master station with a delayed response of a telecontrol device. Background technique [0002] In the substation integrated automation system, the telecontrol device is an automatic device for completing the collection of various information between dispatching and substations and automatically transmitting and exchanging them in real time. It is the basis for the comprehensive automation of power system dispatching. The stability and Data accuracy directly affects the safe and stable operation of the power grid. [0003] After restarting, the remote control device needs to perform data initialization process. During the initialization period, the remote control device establishes communication with the measurement and control device in the station and calls for data. During the period when the initialization is not...
