Frequency converter-based monitoring, diagnostics and control system for artesian well pumps

The article highlights the relevance of energy saving problems on a global scale and need to regulate by state laws production application frequency converters, which allow reduce consumption asynchronous motors 30-60% depending load as result International Energy Agency's targeted policy. Different characteristics controlling motor, is main transmission artesian well pumps, with Straight Frequency Transducer (Variable Transmission) from power grid are compared; principles energy-saving converter (FC) pulse-width modulation, increasing factor (PF-Power Factor) interpreted, principle operation bloc explained, including block diagram. authors report positive results work carried out in oil fields Institute Control Systems ANAS together Cybernetics SDB identification sources finding ways save energy. substantiates urgency creating converter-based monitoring, diagnostic control system for subartesian pumps. At same time, surface underground equipment wells studied, technical requirements an automated early diagnosis optimal their condition formulated, structure new SCADA proposed. A comparative analysis engine directly FC-based Artesian Well Smooth Station (AWSCS) proposed given different cases.
