摘要
北京大兴国际机场作为国际化机场、国家重要发展的新动力源,承担着重要的出行保障任务和客户服务责任,其电能质量的好坏直接影响行李系统、步梯、电梯、灯光和航显系统等敏感性设备的稳定运行。随着电网的发展,由线路故障等原因造成的电压跌落事件更加频发,将在设备生产、运维等方面造成难以估计的损失。电压跌落是一个复杂而随机的问题,电网故障点、故障类型以及末端设备特性都会影响电压跌落的传播特性。为提高敏感设备管理水平并为采取预防性措施提供有效依据,根据IEC 61000-4-11标准进行了电压暂降测试,对末端设备的电能质量敏感度进行测试,量化分析电压跌落监测数据、负荷敏感曲线,为掌握敏感设备耐受水平,提升设备耐受能力,今后设备更新改造、升级及设备选用提供有利依据。
As a new power source with crucial significance to national development,Beijing Daxing International Airport undertakes important travel support tasks and customer service responsibilities.Its power quality directly affects the stable operation of sensitive equipment such as baggage system,stairs,elevators,lighting and flight display system.With the development of power grid,voltage sags caused by line faults and other reasons are more frequent,and voltage sags will cause incalculable losses in equipment production,operation and maintenance.Voltage sag is a complex and random problem.The transmission characteristics of voltage sag depend on multiple facts including fault point,fault type and terminal equipment characteristics of power grid.In order to improve the management of sensitive equipment and provide an effective basis for taking preventive measures,this paper carries out voltage sag test according to IEC 61000-4-11 standard,determines the power quality sensitivity of terminal equipment,and quantitatively analyzes the voltage drop monitoring data and load sensitive curve.This work may provide a favorable basis for obtaining the tolerance level of sensitive equipment,improving the tolerance capacity of equipment,equipment modification,upgrading and equipment selection in the future.
