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 for dispatching a master station with delayed response of a telecontrol device. The first telecontrol startup is completed within the preset first telecontrol startup time; and all measurement and control devices are sequentially carried out in accordance with a preset sequence. Communication database construction, real-time comparison of the measurement and control devices that have completed the communication database construction with the measurement and control devices recorded in the forwarding table of the dispatching master station. If all the measurement and control devices recorded in the forwarding table have been completed by communication, the corresponding The dispatching master station; solve the existing problem of adopting the fixed delay method to respond to the dispatching master station according to the actual power grid operation experience to avoid the error data generated during the initialization process. The fixed delay should be modified synchronously according to the site situation, which is not conducive to on-site maintenance work. The inaccurate empirical value of device delay may lead to technical problems such as misadjustment or miscontrol of the power grid, which will bring huge losses to the power grid.

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...
