Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] The management unit for in-situ protection of intelligent substations of the present invention adopts the following forwarding method to solve the problem of lack of means for sending integrated information of in-situ sub-machines, and improve the reliability of sending component protection multi-sub-machine integrated information, Its overall process is as follows figure 1 shown.
[0030] First, the management unit automatically identifies the component protection sub-machines according to the SCD file of the sub-station, and obtains the information of all component protection sub-machines in the whole station.
[0031] Among them, the management unit automatically obtains the information of all component protection sub-machines of the who...

The invention relates to a management unit for intelligent substation localization protection and a forwarding method thereof. Firstly, according to the SCD file of a substation, information of all component protection subunits of the whole station is obtained, a management unit model is generated, one of the subunits is selected, and a CID model file thereof is derived as a virtual device model.Then, according to the management unit model and the virtual device model, the SCD file of the substation is configured, and the station control layer device communication SCD files are formed. Finally, the corresponding information is uploaded based on the obtained station control layer device communication SCD files. The invention improves the reliability of forwarding the uploaded integrated information multiple component protection sub-units by means of the uploading mode of the virtual device and single device information. Transmission is performed based on the configuration method of three station control layer device communication SCD files so that the requirement of sending information accord to the customized information of different station control layer devices is satisfied. Themanagement unit and the method are favorable for improving the efficiency of intelligent substation maintenance and overhaul.
Description
technical field [0001] The invention belongs to the technical field of automatic control of intelligent substations, and in particular relates to a management unit for in-situ protection of intelligent substations and a forwarding method thereof. Background technique [0002] The smart substation uses intelligent primary equipment to replace conventional primary equipment, and the data transmission form is changed from analog to optical digital, which reduces the secondary cables of the substation and improves the level of information sharing. However, compared with conventional substations, it adds smart terminals. and intermediate links such as merging units. Merging units and smart terminals are generally installed in outdoor HSBC cabinets. The operating environment is harsh, the ability to resist electromagnetic interference is poor, and the failure rate remains high. Moreover, using the communication mode of networking, the action time of protection is longer than that...
