Example Embodiment

[0046] Example one

[0047] This embodiment discloses a graphical configuration method of anti-error lockout logic expressions, such as figure 2 As shown, including the following steps:

[0048] Step 1: Connect the measurement and control device via FTP, and call the current SCD model file of the measurement and control device;

[0049] Step 2: Combine the current SCD model file in the system configuration tool with the SCD file obtained from the measurement and control device;

[0050] Specifically, the two are compared to obtain the data content that exists in the SCD model file of the measurement and control device but not in the system configuration tool, and merge it into the SCD model file of the system configuration tool.

[0051] Step 3: Obtain the merged SCD model file, and analyze the corresponding logical combination relationships of internal signals, external signals, process signals, and output signals corresponding to each IED in the SCD model file to obtain latching logi...

Abstract

The invention discloses an anti-misoperation locking logic expression graphical configuration method and system. The anti-misoperation locking logic expression graphical configuration method comprisesthe following steps: obtaining an SCD model file, carrying out the analysis, and obtaining the locking logic data corresponding to each IED; receiving configuration of primitives and connection relations among the primitives by a user, wherein the primitives comprise an input primitive, an operation primitive and an output primitive; configuring the information bound with the primitives accordingto the locking logic data corresponding to each IED to obtain a graphical logic expression; and generating an anti-misoperation locking file based on the graphical logic expression. The anti-misoperation locking logic expression graphical configuration method obtains a logic expression in a graphical mode, and is convenient for operation, and errors are not likely to happen.

Description

technical field [0001] The invention belongs to the technical field of intelligent configuration of intelligent station equipment, and in particular relates to a graphical configuration method and system for anti-mistake locking logic expressions. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The five-prevention function is specially designed to prevent electrical misoperation accidents in the power system. Through software, a large number of secondary locking circuits on site are converted into basic rules and logic formulas for anti-mistakes in the computer, realizing the digitization of anti-misoperation locking. The maintenance of the basic rules of error prevention and the logic formula of locking is open to the user during the design. The user can carry out the basic rules of error prevention and the logic formula of operation loc...
