摘要
根据超高层建筑供电特点和管理需求,提出了超高层建筑供用电可靠性指标体系和超高层建筑供用电可靠性计算方法——分层搜索算法。该指标体系和搜索算法不仅能对传统用户供电可靠性进行评估,还能对用户内部用电可靠性进行分析,包括用户内部整体可靠性和用户负荷点可靠性,可以对超高层建筑内部实现精益化管理提供技术支持。以一栋由两路电源供电的超高层建筑为例,采用文中提出的指标体系和算法对该建筑进行评价,结果显示,2路并列供电的电源,在同时供电和一路运行、一路检修时,用电可靠性相差不大,而两者的停电损失期望值可相差1.5倍多,该结果能为用户内部检修策略的制定提供有效指导。算例证明了文中提出的指标体系的实用性和分层搜索算法的正确性。
According to the features of power supply and management demand of super high-rise building, a reliability index system for power supply and consumption of super high-rise building and a method to calculate the reliability of power supply and consumption of super high-rise building, namely the hierarchical searching method, is proposed. The proposed method not only can assess the reliability of power supply for traditional consumers, but also can analyze the reliability of interior power utilization of consumers, including the interior overall reliability of the consumer and the reliability of the load point, and provide technical support for implementing the lean management inside the super high-rise building. Taking a certain super high-rise building supplied by two independent power supplies for example, the proposed index system is utilized to assess the power supply reliability of this building, and the assessment results show that there is no obvious difference between the two power supply modes： the building is simultaneously supplied by both power supplies and the building is supplied by one of them and the another one is in the overhaul, however the difference between the expected energy not served （EENS） under the two power supply modes may reach to 1.5 times more. Results of the case study are available for reference to the drafting of the maintenance scheduling for the building; and it is also proved that the proposed index system is practicable and the hierarchical searching algorithm is correct.
