| 摘要: |
| 引入全寿命周期成本和影子价格理论，识别特高压电网成本和社会经济效益组成；并基于与效益相关的各元素影子价格估算公式，深入分析除售电收益外特高压电网所带来的巨大的社会效益。编制投入产出效益流量表，建立基于全寿命周期成本的特高压电网社会效益评价指标；结合灵敏度分析理论，形成适用于特高压电网的社会效益评价方法。以我国某特高压同步大电网2020年规划方案为算例，对比分析了在传统财务成本和考虑全寿命周期成本计算方式下的社会效益评价结果，验证了所提方法的有效性和可行性。 |

| Abstract: |
| The LCC（Life Cycle Cost） and the shadow price theory are applied to recognize the compositions of UHV（Ultra High Voltage） power grid cost and socioeconomic benefit. Beside the revenue of electricity sale，the social benefits from UHV power grid are analyzed based on various benefit-related shadow price theories. The input-output benefit flow tables are established and the LCC-based evaluation indices are built for the social benefits from UHV power grid. Combined with the sensitivity analysis theory，a method suitable for evaluating the social benefits from UHV power grid is put forward. As an example，the evaluated social benefits from a synchronous UHV power grid planed for 2020 are compared between the traditional financial cost method and the LCC-based method，verifying the effectiveness and feasibility of the proposed method. |
