Embodiment 1

[0019] See figure 1 In this example, there is a substation fault information system in the substation of each plant station, which is used to collect the protection action information of the online protection device, the record information of the fault recorder and the configuration information of the two types of devices, and through the two-way communication unit and Wired power data network and master station fault information system for data interaction;

[0020] There is a master station fault information system in the dispatch center, which is connected to multiple sub-station fault information systems through a two-way communication unit and a power data network, and is used to collect the information collected by the fault information system of each sub-station; Carry out scheduling and management;

[0021] The fixed value setting system is equipped with an interface for contacting the fault information system of the master station. The interface is connected to the fault i...

Embodiment 2

[0088] Different from Example 1, this example uses the E language model to describe the setting file given by the setting system, and finally transmits it to the online protection device through the fault information system. At the same time, the fault information system of the master station and the slave station also uses E The language model file stores the fixed value information.

[0089] The format of the E language model file is as follows:

Abstract

The invention discloses a method for realizing cooperative work of a fixed value adjusting system and an on-line device. The method adopts substation fault information systems, main station fault information systems and the fixed value adjusting system, wherein the substation fault information systems are used for acquiring protection action information of an on-line protection device of a station and oscillograph recorded information; the main station fault information systems are connected with a plurality of substation fault information systems and used for dispatching and managing the substation fault information systems and acquiring information of the substation fault information systems; the fixed value adjusting system is used for analyzing and calculating the information acquired by the main station fault information systems and correcting a relay protection fixed value sheet in real time; the fixed value adjusting system is provided with an interface contacted with each main station fault information system, and the interface is in network connection with the main station fault information systems through negative and positive isolation devices to realize bidirectional communication between the fixed value adjusting system and each main station fault information system. The method finishes contact between the fixed value adjusting system and the on-line protection device of the station through network and fault information channels, realizes fixed value on-line adjustment, and can improve the automatic level of power grid operation.

Description

Technical field [0001] The invention belongs to the field of electric power technology, and specifically relates to a technology of electric power system automation. Background technique [0002] In the power network, there is a fault information system. The fault information system is generally divided into the main station and the sub-station. The main station is used to dispatch and connect the sub-stations of multiple plant sites. The main data source of the master station is the sub-station plant-side Protection action information, recorder record information, and configuration information of these two types of devices. Usually the amount of data is very small. When a fault occurs, the amount of data will be extremely large. The fault information contains comprehensive information. Comprehensive analysis based on the data can effectively determine the nature of the fault, which is actually the main basis for judgment. [0003] The function of the fixed value setting system in...
