摘要/Abstract

摘要： 电网资产全生命周期成本（life cycle cost，LCC）是电力系统规划中控制长远成本与短期投资的关键技术。计及可靠性、经济性指标的协调统一及设备不同更替周期对成本计算的影响，针对性地提出一种输电网LCC成本计算模型，以实现面向智能电网规划的方案比选评估。结合电网可靠性分析理论与LCC理论，提出了基于蒙特卡洛模型的可靠性指标计算及量化方法，研究不同负荷类型对可靠性成本影响，并进一步建立了考虑设备更替的电网规划LCC成本模型；最后采用某110 kV变电站的2种规划方案的比选来验证所提出的计及LCC的成本计算模型的准确性和有效性。

Abstract: The life cycle cost of power grid assets is a key technology in power system planning to control long-term cost and short term investment. Considering the effects of reliability, economic indicators and different replacement cycleson the cost calculation, this paper proposes a cost calculation model base on LCC for transmission network to compare and select the schemes of smart grid planning. Meanwhile, in combined with the theory of power network reliability analysis and LCC theory, this paper proposes the reliability index calculation and quantitative method based on Monte Carlo model, studies the effect of different load types on reliability cost, and then establishes the LCC cost model of power grid planning with considering the replacement of equipment. Finally, this paper verifies the accuracy and effectiveness of the proposed LCC cost calculation model through an appropriately example of comparing and selecting of two planning schemes for an 110 kV substation.

Key words: life cycle cost （LCC）, Monte Carlo model, reliability calculation, power grid planning
