Problems solved by technology
However, due to the limitations of hardware technologies such as sensors and power supplies in online monitoring devices at this stage, the collected online monitoring data has problems of low accuracy and reliability. There is a risk that the system may calculate the current carrying capacity of the transmission line inaccurately
In addition, in the design stage of the transmission line, the designers ignored the meteorological differences in local areas in the calculation of the line capacity limit, and adopted the same severe weather standard. difference

The present invention discloses a dynamic compatibilizing system of a transmission line. An online monitoring data acquisition unit acquires online monitoring data on a target transmission line, and the online monitoring data are accessed by a database server by an online monitoring data transmission unit; a line operating data FTP server collects operating data of the target transmission line and the operating data are accessed by the database server; and a statistical weather data FTP server collects statistical weather data of a region where the target transmission line is located and the statistical weather data are accessed by the database server, and a dynamic compatibilizing background unit acquires a maximum current-carrying capacity of the target transmission line according to the online monitoring data of the target transmission line, the operating data of the target transmission line and the statistical weather data of the region where the target transmission line is located in the database server. The dynamic compatibilizing system of the transmission line is capable of acquiring the allowed maximum current-carrying capacity of a target line based on the statistical weather data of a local region where the target line is located, and providing a dynamic compatibilzing basis for scheduling personnel; and data loss can be effectively avoided, and system is reliable and precise.
Description
technical field [0001] The invention relates to the field of electric power technology, in particular to a dynamic capacity increasing system for transmission lines. Background technique [0002] In recent years, my country's economy has continued to grow rapidly, and with the rapid growth of electricity consumption, the situation of power grid transmission has become increasingly severe. In economically developed areas with tight land use and towering high-rise buildings, new transmission lines not only require a long construction period and high investment, but are also more difficult to implement. However, the transmission capacity of existing lines is more strictly limited, and there is often a contradiction between power transmission and power demand. Therefore, while accelerating the construction of a strong smart grid, how to increase the transmission capacity of existing transmission lines also has great practical significance for improving the safe, economical, and...
