- 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.
