A reasonable operation efficiency evaluation method and system for coordinating transmission network security and development

Abstract

The present invention relates to a method and system for reasonable operation efficiency evaluation through coordination of safety and development of a transmission network. The method comprises the following steps: collecting the basic data of a power grid electric power system to be evaluated; improving the power supply load level of the power grid to be evaluated, and analyzing and obtaining the trend data of the power grid to be evaluated in a typical large mode under different load levels after power supply load is increased based on the current actual typical large mode trend data of the power grid to be evaluated; evaluating the relation of a power failure risk level and a power grid utilization efficiency level under different power supply load levels of the power grid; determining the limitation operation efficiency of the power grid to be evaluated according to the relation of the power failure risk level and a power grid utilization efficiency level under different power supply load levels of the power grid and a risk efficiency incremental ratio index; and calculating the reasonable transmission efficiency of the power grid to be evaluated, and performing evaluation of the actual operation efficiency of the power grid to be evaluated. The method and system for reasonable operation efficiency evaluation through coordination of safety and development of the transmission network can be widely applied to the evaluation of the power grid transmission network utilization efficiency.

Description

technical field [0001] The invention relates to a transmission network analysis and evaluation method, in particular to a reasonable operation efficiency evaluation method and system for coordinating transmission network security and development. Background technique [0002] As an important public infrastructure, the power grid plays an important role in optimizing resource allocation, ensuring energy security, and meeting the needs of economic and social development. It is required to have a reasonable structure, flexible operation, and be able to provide safe, reliable, and high-quality power supply. At the same time, as a self-financed operating enterprise, the power grid company requires long-term and stable development and viability, and the efficient use of grid assets plays an extremely important role in saving grid investment and bringing out the benefits of assets. However, the continuous improvement of efficiency may lead to the decrease of power grid safety margi...

Problems solved by technology

However, the existing research on the evaluation of transmission network utilization efficiency mainly establishes the load rate indicators of power grid lines and transformers. There are still few researches and results on the analysis and evaluation of reasonable operation efficiency, lack of scientific theoretical guidance and practical operation methods, and no consideration The constraints of power grid security and development cannot truly obtain reasonable power grid operation efficiency, let alone provide guidance for power grid development and operation
