Abstract
A plug and play method for a travelling wave fault location system belongs to the field of electric power automation. Through the method, a distance measuring main station system does not need to manually create whole situation topological parameters of a monitored grid and parameters of distance measuring terminals, but each distance measuring terminal builds and stores the information of a line monitored by the distance measuring terminal and opposite terminal transformer substation. When the distance measuring terminals are electrically connected to a communication network where the main station is, a distance measuring main station can automatically identify the condition that the distance measuring terminals are on line, and the registrations of the distance measuring terminals on the distance measuring main station are realized. Meanwhile, the main station automatically reads the configuration information of each distance measuring terminal, and automatically builds a grid whole situation topology needed by the main station according to grid local topological information stored in each distance measuring terminal; the distance measuring terminals and the lines are monitored by the distance measuring main station, thus achieving the plug and play effect of the distance measuring terminals in the distance measuring main station system. When parameters of the lines monitored by the distance measuring terminals change, the whole situation topology of the main station is rebuilt by rereading the configuration parameters of the distance measuring terminals in time through the distance measuring main station.

Fig. 1 ~ 3 are most preferred embodiments of the present invention, and below in conjunction with accompanying drawing 1 ~ 3, the present invention will be further described.
As shown in Figure 3, the plug and play method of travelling wave ranging system, comprises the steps:
Step 1, the electrical network local topology of configuration distance ranging terminal 3;
As shown in Figure 1, be expert in ripple range measurement system, comprise multiple distance measurement Master station 1 and multiple distance ranging terminal 3, distance ranging terminal 3 and distance measurement Master station 1 are connected by communication network 2 and realize communication, and distance ranging terminal 3 is installed in transformer station.Each distance ranging terminal 3 all carries out the configuration of electrical network local topology by distance ranging terminal configuration tool.
Electrical network local topology refers to the line parameter circuit value that single distance ranging terminal 3 is monitored, affiliated transformer station and circuit opposite end transformer station.Each distance ranging terminal, when installation is implemented, adopts Master Station Software or distance ranging terminal configuration tool to configure its electrical network local topology, and only need configure the circuit of its monitoring, configure simple and convenient.Except realizing electrical network local topology by distance ranging terminal configuration tool to the distance ranging terminal 3 in transformer station, also by the electrical network local topology of distance measurement Master station 1 distant place configuration distance ranging terminal 3, then can be issued in corresponding distance ranging terminal 3 by communication network 2.
In topological structure of electric schematic diagram as shown in Figure 2, the electrical network local topology of the distance ranging terminal 3 installed with B transformer station 5 and B transformer station 5 is set to example: the circuit that the distance ranging terminal 3 of B transformer station 5 is monitored comprises the first outlet 10, second outlet 6, the 3rd outlet 11 and the 4th outlet 12 4 articles of circuits.Wherein the local terminal transformer station of the first outlet 10 is B transformer station 5, and opposite end transformer station is A transformer station 4; The local terminal transformer station of the second outlet 6 is B transformer station 5, and opposite end transformer station is C transformer station 7; The local terminal transformer station of the 3rd outlet 11 and the 4th outlet 12 is B transformer station 5, and opposite end transformer station is D transformer station 8.After specify that the circuit connection information that the distance ranging terminal 3 of B transformer station 5 is monitored, above information is stored with the form of XML file, be issued in the distance ranging terminal 3 of B transformer station by distance ranging terminal configuration tool, thus just complete the electrical network local topology configuration of distance ranging terminal 3 in B transformer station 5.The power network topology collocation method of A transformer station 4, C transformer station 7, D transformer station 8 and E transformer station 9 is identical.
