摘要
从目前国内电网建设所倡导的全生命周期成本管理的视角,分析了全数字化变电站二次系统的全生命周期成本及综合效益,给出了实用的成本模型和计算公式,并对各项成本因素进行了分解说明,并结合某实际数字化工程改造前后的效益对比情况,说明全数字化变电站是变电站自动化的技术发展方向。
The paper analyzes total life cycle costs and the comprehensive benefits in secondary system of digital substation from the view of total life cycle costs(LCC)management which is promoted in power system construction,gives the practical LCC model and formula,and also explains LCC element.It presents that digital substation is the trend of substation automation using benefit contrast of an actual digital substation project.
