CN105427049A 基于分割理论的电网工程前期策划与运维阶段预警方法 无效 - 驳回

基于分割理论的电网工程前期策划与运维阶段预警方法
摘要：
本发明为基于最优分割理论的电网工程前期策划与运维阶段投资预警方法，首先，针对电网工程前期策划与运维阶段的资金计划与实际情况，建立投资监控点集；其次，收集投资监控点样本数据，利用最优分割理论，确定初步预警阈值区间；然后，引入判别分析,修正预警阈值区间；最后，根据电网工程项目实际前期策划与运维阶段的投资计划与实际情况，将监控的数据进行代入测算，得出预警情况，动态监控，直至电网工程全寿命期结束。本发明能够有效地进行投资风险预警，从而使电网工程项目在前期策划与运维阶段的投资风险进行及时的预警，为电网工程项目的投资风险控制的研究提供一定的基础。
摘要（英）：

The invention discloses an optimal segmentation theory based power grid project pre-planning and operation and maintenance stage investment prewarning method. The method comprises: firstly, for a fund plan and an actual condition of a power grid project pre-planning and operation and maintenance stage, establishing an investment monitoring point set; secondly, collecting investment monitoring point sample data and determining a preliminary prewarning threshold range by utilizing an optimal segmentation theory; thirdly, introducing judgment and analysis to correct the prewarning threshold range; and finally, according to an investment plan and an actual condition of an actual power grid project pre-planning and operation and maintenance stage, calculating monitoring data by substitution to obtain a prewarning situation, and performing dynamic monitoring until the total lifetime of a power grid project is up. According to the method, the investment risk can be effectively prewarned, so that the investment risk of the power grid project during the pre-planning and operation and maintenance stage can be prewarned in time and a certain foundation is provided for the research on investment risk control of the power grid project.
