Embodiment 1

[0067] Such as Figure 1-6 As shown, the invention of this example is a transmission line protection module generation system and its generation method; the system includes:

[0068] The protection algorithm component unit provides users with protection algorithm components;

[0069] Protect the logical component unit and provide the logical component to the user;

[0070] Visual interface unit to generate transmission line protection module;

[0071] The monitoring unit monitors and tests the matching relationship between the action behavior of the transmission line protection module and the logic components.

[0072] For line protection algorithm components can be divided into two categories. One is the characteristic quantity algorithm component, including the amplitude component, phase component, power component, impedance component, sequence component, etc. of the electrical quantity; the other is the protection action criterion or action equation pre-low-pass filter (...

Abstract

The present invention relates to a system for generating a transmission line protection module and a generation method thereof. The method comprises a step of creating a protection algorithm element, a step of selecting a logic component, a step of creating a transmission line protection module through the combination of the protection algorithm element and the logic component, and a step of monitoring the matching relation between the action behavior of the transmission line protection module and the logic component. According to the technical scheme provided by the invention, different protection functions can be realized according to different combinations to adapt different project needs, and the realization of the module integration of multiple protection devices is facilitated.

Description

Technical field: [0001] The invention relates to the field of relay protection, and more specifically to a configuration-based generation system for a power transmission line protection module and a method for generating the module. Background technique: [0002] In the power system, relay protection is the key to ensure the safe operation and reliable power supply of the power system. When the power grid fails, if the relay protection fails to operate correctly, it will not only expand the fault of the power system, but may even cause the entire power grid to collapse due to an adverse chain reaction, resulting in a large-scale power outage, affecting people's normal life, economic development and serious impact on social stability [0003] However, data prove that as many as 75% of power system safety accidents are caused by relay protection device failures. Among them, the system defect of the relay protection device has a significant impact. [0004] Recently, there a...
