摘要:
北京某大型给水厂配水泵房设计规模为50×104 m3/d，根据供水需求设计了9套10 kV水泵机组。10 kV水泵机组配套电气设备较多，其相互间联锁控制较为复杂，同时，作为给水厂中的重资产及关键工艺设备，其安全、可靠的运行直接影响区域的供水安全。分别从直接启动、软启动和变频启动三种不同的启动方式的角度详细地阐述了水泵机组的联动控制设计及要求，包括各电气设备的启动及停止顺序、相互间联锁关系、采集及发送信号要求和通信线缆要求等。该水泵机组自2020年6月投入运行，成功实践了这三种启动方式下的水泵机组联动控制策略，至今运行稳定、可靠。
Abstract:
The design scale of a water distribution pump room belonged to a large water supply plant in Beijing is 50×104 m3/d. According to the water consumption demand, 9 sets of 10 kV water pump units are designed. There are many ancillary electrical equipments of a pump unit with voltage of 10 kV, and their interlocking control is relatively complex. In addition, as a valuable asset and key equipment in water supply plant, the safe and reliable operation of pump units directly affects the safety of regional water supply. The design and requirements of the water pump unit linkage control were illustrated in detail from the perspective of three different starting modes: direct start, soft start and variable frequency start, including the starting and stopping sequence of each electrical equipment, interlocking relationship between each other, acquisition and sending signal requirements and communication cable requirements. The water pump unit has been put into operation since June 2020, the linkage control strategy of the pump units with the three starting modes has been successfully practiced, and the operation is stable and reliable up to now.
