Problems solved by technology

[0006] After searching the existing technical literature, it is found that the patent application "Auxiliary decision-making system for distribution network planning scheme" (patent application number: 200710170431.2), "Comprehensive decision-making method for urban power grid planning scheme based on data envelopment analysis" (patent application number: 200610118879.5) mainly focused on distribution network planning in the field of electric power technology, but did not involve transmission network planning. Because there are fundamental differences between distribution network planning and transmission network planning in terms of planning principles, design ideas, research objects and technical implementation, Therefore, it is difficult to guide the development of transmission planning
Patent application "Transmission Network Planning Method Based on Deterministic Bi-level Programming Model" (Patent Application No. 200710170435.0) and "Method of Establishing Transmission Network Planning Model in Uncertain Environment" (Patent Application No.: 200810016543.7) mainly studied the transmission network planning The reliability problem in the project does not involve the life of power transmission and transformation equipment and the dynamic changes in the value of land resources, and the planning results are difficult to reflect the comprehensive and long-term benefits of the planning scheme

Embodiment Construction

[0021] The present invention will be described in detail below with reference to the drawings and embodiments.

[0022] In order to quantitatively evaluate several transmission grid planning schemes drawn up based on expert experience and regional power balance, the present invention provides a transmission grid planning scheme comparison and selection system based on the integrated planning cost (IPC) model. The comprehensive planning cost model is a method that draws on the theory and method of asset life cycle, comprehensively considers economic and social factors, determines the total expenditure during the calculation period based on the grid risk index and land resource index, and converts the total expenditure into The comprehensive planning cost is a dynamic planning model based on the selection of the plan. The comprehensive planning cost model includes two levels of meaning: on the one hand, in the process of comparison and selection in the planning stage, guided by the...

Abstract

The invention relates to a comparing and selecting system of a power transmission network planning scheme, which is characterized by comprising a basic planning data collecting module, a power transmission network planning scheme input module, a feasibility check module, a comprehensive planning cost calculating module and a scheme comparing and selecting module; the basic planning data collectingmodule collects basic planning data; the power transmission network planning scheme input module inputs the power transmission network planning schemes and power transmission planning conditions to be compared and selected; the feasibility check module carries out electric calculation and check on the power transmission planning scheme to be compared and selected according to the basic planning data and the power transmission network planning conditions; and the comprehensive planning cost calculating module calculates the comprehensive planning cost of the power transmission network planningschemes meeting the electric calculation check conditions, the calculated results are input to the scheme comparing and selecting module and comparison and selection of the power transmission networkschemes are carried out according to calculated comprehensive planning cost. The comparing and selecting system of the power transmission network schemes is beneficial to further improving the safe reliability of the planning schemes and simultaneously providing scientific basis for establishing risk input strategies and control measures in the power industry.

Description

Technical field [0001] The invention relates to the field of transmission grid planning, and particularly relates to a system for comparing and selecting transmission grid planning schemes. Background technique [0002] In many years of practice, the planning and design of the transmission network has formed a planning and design system that is compatible with economic and social development and is still in use today. Limited by the shortage of funds for power grid construction in the past, the traditional planning and design system particularly emphasizes the weight of initial investment in the selection of plans. With the rapid economic and social development, power grid companies have begun to pay more attention to the comprehensive performance of the power grid in the long life cycle, and actively adopt high-tech and new equipment to continuously improve the reliability and social benefits of the power grid. If the traditional planning and design comparison system is still u...
