Electric drive control system of pumping unit
Figure №1
The main system element is frequency converter “ ACS 800”, which provides as follows:
- drive acceleration and slowing with set pace
- adjustable speed control in accordance with given value
- desired protections of electric drive and converter components
Figure №2
Regulating and control system is realized on logical modules LOGO, which allow realizing as follows:
- Automatic regulation algorithms
- Start and break algorithms
- Protection and interlock system
- Visualization of basic parameters
