Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] Such as figure 1 As shown, the secondary security operation support system can be logically divided into three layers, namely: application layer, service layer, and interface layer.

[0044] The application layer serves the operators, and completes the security isolation of the secondary equipment and the secondary system through the three functions of ticket drafting, rehearsal, and execution. The service layer provides support for the application layer.

[0045] Among them, the anti-mistake detection module supports the graphical ticket drafting module, which is used to detect whether the secondary security measures in the process of graphical ticket drafting violate the rules set in advance; the secondary system simulation module supports rehearsal, through the simulated secondary system , to provide support for the correctness analysis of t...

Abstract

The invention discloses a secondary safety measure support system in operation and maintenance of an intelligent substation and a construction method. The system comprises an application layer, a service layer and an interface layer, wherein the application layer is used for generating a secondary safety measure in a graphic simulation process and finishing safety isolation of secondary devices and a secondary system; the service layer is used for establishing a secondary system model, simulating and rehearsing the secondary safety measure by utilizing the secondary system, detecting whether the secondary safety measure in the graphic simulation process violates a rule set in advance, and judging the effectiveness of the secondary safety measure; and the interface layer obtains board pressing and loop states from a network analyzer and converts board pressing operation sent by a board pressing state check module into operation information identifiable for an integrated information platform. According to the system, for secondary safety measure establishment, the board pressing and loop states are visually seen and the interoperation relationship of the secondary devices in the whole secondary system can assist operating personnel to establish the secondary safety measure.

Description

technical field [0001] The invention relates to a secondary safety measure support system and construction method in the operation and maintenance of an intelligent substation. Background technique [0002] In recent years, with the large-scale construction and operation of smart substations, and the rapid increase in design and commissioning related infrastructure capabilities, provincial grid companies have gradually shifted the focus of smart substations from more mature planning and construction to operation and maintenance. Among them, the secondary safety measures, as the safety defense line between the equipment to be isolated and the operating equipment, are related to the safe and stable operation of the power grid, and occupy an important position in the operation and maintenance of smart substations. [0003] Since the smart substation adopts the IEC61850 standard system, its communication mode and equipment form are different from conventional substations. The m...
