Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] Please refer to figure 1 , the present invention provides a method for online setting of power distribution automation terminal protection fixed value, comprising the following steps:
[0024] 1) GOMS draws up the value application form, triggers the initial process of value setting, and generates an information list for the terminal information ledger that needs to be set;
[0025] 2) The master station system of distribution automation receives the application form for setting value sent by the GOMS system through the data interaction bus. After reviewing the application form, GOMS sends the XML format file to the master station system of distribution automation in the form of WebService. After receiving the data sent by the GOMS system, the power distribution master station system sends a confirmation message to the GOMS system.

The invention relates to a method for online setting and calculation of power distribution automation terminal protection setting value, comprising: writing a setting application form by GOMS and triggering the initial setting process; transmitting the information of the application form to the DMS system through an information interaction bus ; Determine the electrical topological relationship of the model by the DMS system; analyze the rating application form according to the electrical topology relationship and associate the 10kV substation outlet switch and busbar; analyze the rating application form feeder information according to the electrical topology relationship to form a protection diagram, and display it on the WEB interface ;According to the electrical topological relationship, intelligently distinguish the properties of the switch to form a calculation plan; intelligently query the power supply range and power supply path according to the electrical topology relationship, and calculate the fixed value of the switch; cooperate with the upstream and downstream setting value configuration according to the electrical topology information, and correct the switch protection setting value; setting calculation The results are cross-checked online, and the calculation results are synchronized with the GOMS system; the valuation notices are archived, stored and compared in the system, and the automatic setting calculation and overall management of the valuation are established.
Description
technical field [0001] The invention belongs to the field of electric power system automation, and in particular relates to an online setting method for protection fixed value of distribution automation. Background technique [0002] With the continuous construction of the power system and the advancement of various practical functions, the primary grid of the distribution network changes frequently, and the number of terminals providing relay protection for it increases year by year. At present, the terminal fixed value management function of the automation system is weak, and there is a lack of unified and efficient fixed value management methods. There is no terminal setting module for overall management, resulting in the dispersion of relevant information, and it is impossible to conduct comprehensive monitoring of the protection terminals of the automation system. Maintenance personnel cannot fully grasp the protection terminal information of the entire system in a tim...
