Embodiment

[0061] Such as figure 1 As shown, a comprehensive economy and safety transmission line utilization rate improvement platform is characterized in that it includes a database module 1, an input module 2, an analysis and evaluation module 3 and an output module 4 connected in sequence, and the input module 2 Obtain the initial load of the transmission line, power flow distribution and power equipment data from the database module 1, and send it to the analysis and evaluation module 3. When the load loaded on the transmission line exceeds the safe value, the analysis and evaluation module 3 calculates the safety and economic costs paid and The economic benefit obtained, and compare the growth rate of the two, if the former is less than the latter, then increase the load of the transmission line, otherwise stop increasing the load of the transmission line, so as to optimize the utilization of the transmission line, the security economic cost is When the transmission line is partial...

Abstract

The invention relates to a power transmission line utilization rate improving platform taking economic benefits and safety into integrated consideration. The platform comprises a database module (1), an input module (2), an analysis evaluation module (3) and an output module (4) which are successively connected, wherein the input module (2) obtains a power transmission line initial load, trend distribution and power equipment data from the database module (1) for transmitting to the analysis evaluation module (3), the analysis evaluation module (3) gradually increases the load loaded by a power transmission line, when the load exceeds a safety value, calculates a safety economic cost paid by the power transmission line and economic benefits obtained by the power transmission line and compares increment speeds of the two, and the output module (4) outputs a power transmission line utilization rate at the moment. Compared to the prior art, the actual operation condition of the power transmission line is taken into full consideration, the calculation precision is high, and economic benefits of the power transmission line are improved.

Description

technical field [0001] The invention relates to a platform and method for improving the utilization rate of transmission lines, in particular to a platform and method for improving the utilization rate of transmission lines with comprehensive economy and safety. Background technique [0002] In the actual operation of the power grid, its operation mode is subject to factors such as safety, stability, and policy, and the power flow of the line is often far below its capacity, resulting in a low utilization rate of the transmission line. The utilization rate of transmission lines is closely related to the economy and safety of power transmission lines. If the utilization rate is high, the upgrading and transformation of transmission lines will be appropriately delayed, the investment in transmission lines is low, and the economy of transmission lines is better; at the same time, higher utilization of transmission lines The rate will make the ability of the transmission line to...
