面向电网产能优化的设备利用效率评价及应用

摘要

It is of great practical significance to establish the evaluation system of power equipment utilization efficiency aiming at power grid capacity optimization for collaboration of power grid planning and construction.An evaluation system of power equipment utilization efficiency aiming at power grid capacity optimization is introduced.Four major evaluation indices,including capacity-load ratio,maximum load rate,annual equivalent mean load rate and annual mean utilization time,and power grid capacity optimization limits are given.Considering the key factors influencing utilization efficiency,and a capacity optimization method is adopted to en-hance the overall utilization efficiency.Case study in Yunnan power grid verifies the reasonability and effectiveness of the evaluation system and the optimization method proposed in this paper.%建立面向电网产能优化的设备利用效率评价体系，对于指导电网协同规划与建设具有重大的现实意义。提出了面向电网产能优化的设备利用效率评价体系，给出了容载比、最大负载率、年等效平均负载率及年平均利用时间，和电网产能优化目标限值等4大类评价指标，考虑影响电网设备利用效率的关键因素后，采用电网产能优化的方法提高电网整体利用效率。最后以云南电网为例验证了本文所提出的电网产能利用评价体系和优化方法的合理性和有效性。
