Design and Implementation of Computer Aided System for Improving Transmission Capacity of Power Grid

Research on capacity expansion of heat stable transmission based on on on-line monitoring is the main technical solution for dynamic capacity enhancement of transmission lines. In the past, there was a lack of late disposal application and system integration of the calculation results. In this paper, based on the mainstream energy management system (D5000, OPEN3000) platform and on-line dynamic monitoring and capacity-increasing technology, taking into account the meteorological forecast information of the geographic area where the line channel is located, the on-site monitoring device is deployed to collect on-site wire and environmental information, and the collected information is transmitted to the backstage monitoring master station through APN network transmission technology, and the heat stable transmission capacity of the system is measured. The calculation service module is used to calculate the capacity increase, and the information of the allowable carrying capacity of transmission lines in three grades, high, medium and low, and the temperature rise time of transmission lines after the transfer of large tidal currents are obtained, which provides technical means for the regulators to enhance the transmission capacity of the power grid.
