  The lightning protection terminals 100, 200, etc. are installed in a management office that manages facilities such as substations, and when considering lightning protection measures, facility ID data 30 of the facilities that perform lightning protection measures is input. At the same time, the facility ID data 30 is transmitted to the lightning protection countermeasure support server 10, and the lightning countermeasure data 12 transmitted from the lightning protection support server 10 is displayed.

  The lightning protection support server 10 extracts the lightning frequency data 14 and the environmental data 16 from the lightning frequency database 13 and the environment database 15 based on the facility ID data 30 transmitted from each lightning protection terminal 100, 200, etc. Based on these three data, the lightning protection data 12 is extracted from the lightning protection database 11, and the lightning protection data 12 is transmitted to the lightning protection terminals 100, 200, etc. The lightning protection support server 10 may be connected to each lightning protection terminal 100, 200, etc. via the Internet or may be connected via another network such as a dedicated line. Further, the lightning protection support server 10 and each of the lightning protection terminals 100, 200, etc. may be connected via dedicated software or connected via a general browser. Furthermore, the lightning protection countermeasure support server 10 and each of the lightning protection terminals 100, 200 need not be special hardware, and may be a general personal computer or the like.

  Here, the lightning protection countermeasure support server 10 and the lightning protection countermeasure terminal 100 which constitute the lightning protection countermeasure support system 1 will be specifically described with reference to FIG. In the following, it is assumed that the lightning protection countermeasure support server 10 is connected only to the lightning protection terminal 100.

  As shown in FIG. 2, the lightning protection support server 10 stores a lightning protection database 11 in which lightning protection data 12 is stored, a lightning frequency database 13 in which lightning frequency data 14 is stored, and environmental data 16. A lightning protection measure extracting means 20 for extracting the lightning protection data 12 based on the environmental database 15, the lightning frequency data 14 and the environmental data 16, and data updating for updating each data to the latest data at a predetermined timing. Means 21 and data correction / correction means 22 for correcting or correcting each data to correct data.

  The lightning protection database 11 stores lightning protection data 12. The lightning protection data 12 is data as shown in FIG. 3, for example. Here, the lightning protection measure ID is an authentication number assigned to each lightning protection measure data 12. The frequency of thunderstorms ranks the frequency of occurrence of thunderstorms, with A being the highest frequency of thunderstorms, C being the lowest frequency of thunderstorms, and B being the frequency of occurrence of thunderstorms in between. It shows that. The environmental standard indicates the location environmental standard of the target facility. Measures for all tracks are lightning protection measures for equipment around the target facility. The equipment-specific measures are lightning protection measures performed for each equipment provided in the target facility. In other words, lightning protection measures for “significant cables”, which are facilities with a lightning strike frequency of “A” and an environmental standard of “supply path to the top load of satellites, etc.” If there is a need for lightning protection measures for the surrounding equipment, the lightning protection measures are “installation of overhead ground wires and lightning arresters at 200 m intervals” in the surrounding equipment. It shows that.

  The lightning strike frequency database 13 stores lightning strike frequency data 14. The lightning strike frequency data 14 is, for example, as shown in FIG. The facility ID is an authentication number assigned to each facility, and corresponds to the facility ID data 30 described above. The frequency of lightning strikes is the same as described above. In addition, the lightning strike frequency data 14 is obtained by dividing the area where the facility exists into predetermined sections and, based on the past lightning strike data for each section for a predetermined period, LLS).

  The environment database 15 stores environment data 16. The environmental data 16 is, for example, as shown in FIG. The environment is data indicating the environment where the facility is located. The facility ID is the same as described above.

  The lightning protection countermeasure extraction unit 20 functions to extract the lightning protection countermeasure data 12 based on the lightning strike frequency data 14 and the environment data 16. For example, when extracting the lightning protection data 12 for the voltage regulator of the facility whose facility ID is “0001”, the lightning frequency data 14 of the facility whose facility ID is “0001” from the lightning frequency database 13 shown in FIG. Is “A”, and the environmental data 16 of the facility whose facility ID is “0001” is “satellite” from the environmental database 15 shown in FIG. 5, and therefore, from the lightning protection database 11 shown in FIG. The lightning protection data 12 “installed in a lightning arrester (in principle, within 50 m)” is extracted. Furthermore, when lightning protection measures are required for the surrounding facilities, “installation of overhead ground wires and lightning arresters in the surrounding facilities at intervals of 200 m” is extracted.

  The data update unit 21 functions to update the lightning protection data 12, the strike frequency data 14, or the environmental data 16 at a predetermined timing. For example, when a part of the lightning protection data 12 or the environmental data 16 is changed, the lightning protection data 12 or the environmental data 16 is immediately updated to the latest data or based on new lightning data at the end of the fiscal year. When new lightning frequency data 14 is created by the lightning location system (LLS), the lightning frequency data 14 is updated to the newly created lightning frequency data 14 at the beginning of the next fiscal year. . By providing the data update means 21, it is possible to support the formulation of lightning protection measures based on more appropriate data.

  The data correction / correction means 22 functions to correct / correct the lightning protection data 12, the strike frequency data 14, or the environmental data 16. For example, when there is an input error of each data, the data is manually corrected / corrected, or the lightning frequency data 14 is manually corrected / corrected based on the experience of the operator. The data correction / correction means 22 can support the formulation of lightning protection measures based on more accurate data.
