【正文】 ed according to medium voltage substation (60 kV and below), highvoltage substations (110 ~ 220 kV), EHV Substation (330 ~ 765 kV) and Ultra High Voltage Substation (1000 kV and above). In electric power system according to their status as a hub substation can be divided into the middle substation substations and terminals. This requires a substation part of economic rationality, the second part of safe and reliable, the only way to the normal operation of substation work services for the national economy. There are stepup transformer stepdown transformer substation and two broad have been equipped with various protection devices, these devices are based on lower shortcircuit load to a maximum load conditions, such as configuration settings and, therefore, in the event of the failure was similar to the specific circumstances under to judge by the system should automatically trip protection, and now the protection of the whole trip has been a very short time, the lifting of the fault, the system will automatically reclosing devices and the gateway to restore power quickly. This is to protect the lower the load is very favorable. This will not only protect the safety of the load equipment is in favor of extending the service life and reduce equipment investment, and improved reliability of electricity supply, which is to improve the efficiency of industrial and agricultural production is very have been equipped with various protection devices, these devices are based on lower shortcircuit load to a maximum load conditions, such as configuration settings and, therefore, in the event of the failure was similar to the specific circumstances under to judge by the system should automatically trip protection, and now the protection of the whole trip has been a very short time, the lifting of the fault, the system will automatically reclosing devices and the gateway to restore power quickly.

Electricity supply reliability and other fields, can improve people39。附錄Ⅲ英文翻譯A prehensive overview of substationsA
