Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 2 Shown is the overall block diagram of the present invention. The flexible logic module is the core module of the present invention, which has the functions of logical equation compilation and calculation. The calculation result of the protection module, the switch input, the digital input, and the virtual input are used together as the input of the flexible logic. The final result is saved in the virtual output.

[0025] A flexible logic online compiling module, a flexible logic control module and a flexible logic online monitoring module are added in the device. Among them, the online compilation module is responsible for translating the edited flexible equations into CPU executable units when the device is running; the control module executes the translated flexible equations and outputs the execution results; the...

Abstract

The invention provides a flexible logic realization method capable of being monitored of an intelligent relay protection device. A flexible logic on-line compiling module, a flexible logic control module and a flexible logic on-line monitoring module are added in the device. Logic equations can be translated into codes that can be executed by a CPU through flexible logic on-line compilation, The flexible logic control module can effectively execute the logic equations and output results, and the flexible logic on-line monitoring module monitors flexible logic execution on a real-time basis. Host computer software is compiled to realize editing of the logic equations, and the flexible logic execution result can be checked on a real-time basis, thus greatly increasing the flexibility of protection device software and improving the applicability of protection device commissioning.
