SELECTION OF THE POWER OF STATIC CONDENSERS TO ENSURING THE OPERATION OF PUMPING UNITS OF THE AMU-ZANG-I PUMPING STATION

Аннотация

This article determines the available number of pumping units for a given parameter of the supply transformer based on the degree of loading of the electric motors of the pumping units. For this purpose, the operating modes of electric motors together with their pumps were studied. Considering that the maximum load of the transformer in terms of power will occur with the greatest number and maximum load of parallel operating pumping units in each pressure pipeline for the calculation we take the case of parallel operation of four pumps on a common pipeline. The calculation uses the load characteristics of asynchronous motors taken in factory laboratory conditions to determine the total active power consumed by the pumping station motor from the supply transformer. Based on the calculations made, recommendations are given to ensure the normal operation of all pumping units of the pumping station and the size of the additionally switched-on reactive power source.
