Summary:PROBLEM TO BE SOLVED: To provide a maintenance plane support system of a power generation unit group capable of transversely considering loss costs across a plurality of power generation units, and reducing total costs by the efficient planning of a maintenance plan as a whole power generation unit group.SOLUTION: A maintenance plan support system S1 of a power generation unit group configured to support a maintenance plan of a power generation unit group consisting of a plurality of power generation units comprises: an efficiency arithmetic part 201 for analyzing efficiency of each of those power generation units; a fuel loss cost arithmetic part 202 for calculating fuel loss costs due to excessive consumption of fuel accompanied by a decrease in efficiency; a loss cost arithmetic part 204 for calculating loss costs of each power generation unit on the basis of the fuel loss costs and maintenance work costs for improving efficiency; and a total cost arithmetic part 205 for calculating total costs of the whole power generation units on the basis of the loss costs.SELECTED DRAWING: Figure 1 【課題】損失コストを複数の発電ユニットに亘って横断的に考慮することができ、発電ユニット群全体としての効率的な保守計画の立案により総コストの低減を図ることができる発電ユニット群の保守計画支援システムの提供を目的とする。【解決手段】本発明の発電ユニット群の保守計画支援システムＳ１は、複数の発電ユニットからなる発電ユニット群の保守計画を支援する発電ユニット群の保守計画支援システムであって、発電ユニットそれぞれの効率を解析する効率演算部２０１と、効率の低下に伴う燃料の過剰消費による燃料損失コストを求める燃料損失コスト演算部２０２と、燃料損失コストと効率の改善のための保守作業費用とに基づき発電ユニットごとの損失コストを求める損失コスト演算部２０４と、損失コストに基づき複数の発電ユニット全体の総コストを求める総コスト演算部２０５とを備えていることを特徴とする。【選択図】図１
