特高压作为一种新的电压等级,需要建立科学客观的技术经济方法与指标。建立了特高压电网技术经济评价方法,在将特高压电网发展评估划分为协调、可靠、优质、高效、经济、社会共6个子系统的基础上,分别建立了三级指标,并进行了解释说明。以特高压电网规划为例,应用指标体系对特高压电网各阶段的目标网架进行了技术经济评价。 As a new voltage level, UHV needs to establish a scientific and objective technical and economic method and index. A technical and economic evaluation method for UHV power grid was established. Based on the six subsystems of coordination, reliability, quality, efficiency, economy and society, the assessment of UHV power grid development was divided into three levels and their explanations were given . Taking the UHV power grid planning as an example, the technical and economic evaluation of the target grid at each stage of UHV power grids is made using the index system.
