Embodiment Construction
[0023] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0024] The invention provides a secondary safety diagnosis system for intelligent substations, such as figure 1 As shown, it includes the scene analysis module, acquisition module and diagnosis module. The scene analysis module is used to divide the operating status of the protection device and the safety automation device according to the type of the protection device and the safety automation device, the inspection mark and the status of the pressure plate. For the operation scene, signal scene, exit scene and maintenance scene, divide the merging unit and the intelligent terminal into the operation scene and the maintenance scene, and formulate the secondary security diagnosis rules corresponding to each scene according to the divided scenes; the acquisition module is used for Real-time collection of operating status information of protection d...

The invention provides a two-time safety measure diagnosing method and system for an intelligent substation. Operating states that a protecting device and a safety automation device are in are dividedinto an operating scene, a signal scene, an exit scene and an overhauling scene. Operating states that a merging unit and an intelligent terminal are in are divided into the operating scene and the overhauling scene. Two-time safety measure diagnosing rules corresponding to all the scenes are formulated according to the divided scenes. Operating state information of the protecting device, the safety automation device, the merging unit and the intelligent terminal is collected in real time, according to the order of the scene rules, the collected operating state information and the corresponding two-time safety measure diagnosing rules are compared, and whether the two-time safety measure diagnosing rules are met or not is judged. According to the two-time safety measure diagnosing methodand system, the diagnosing purpose is clear, the diagnosing rules are perfect, diagnosing for two-time equipment is accurate, the two-time safety measure executing process is monitored effectively andreminded intelligently, and reliable isolating of to-be-overhauled equipment and safety and reliability of the equipment are ensured.
Description
technical field [0001] The invention belongs to the technical field of electric power system automation, and in particular relates to a method and system for diagnosing secondary safety measures of an intelligent substation. Background technique [0002] Secondary safety measures, as the technical support for on-site work such as defect elimination, maintenance, upgrading, reconstruction and expansion after the substation is put into operation, are of great significance to ensure the safety of the primary and secondary equipment of the smart substation and the stable operation of the power grid. [0003] The pressure plate and the circuit are the main safety isolation objects in the secondary safety measures, but in the secondary system of the intelligent station using optical fiber communication and IEC61850 information modeling, the visible hard wiring becomes optical fiber, and the real terminal becomes a virtual terminal. The hard platen has changed into a soft platen, a...
