Submersible Pump Intelligent Protection System

In this paper, by analyzing characteristics and working principles of ad-vanced electric submersible pump protectors and motor protectors, research and developed a general electric submersible pump protector.At present, the electric submersible pump is widely used in underground mining process. With protection not correctly used, electric submersible pumps usually break down in the industrial production process, causing direct or indirect loss. The protection of electric submersible pump is being widely concerned.In recent years, as ARM and embedded technology in the field of industrial monitoring and control field developed rapidly, many motor protector designs based on embedded system. Some multifunctional microprocessor motor protec-tors are designed base ARM9 and Linux system with some pieces of RAM out-side. This system designed base ARM7 with Code to streamline, structure com-pact, and conserved resources. Data processing uses a quasi-synchronous algo-rithm and the advanced recursive Fourier algorithm to ensure a high accuracy. System uses LPC2131 for center processing, Wellhead protection of the terminal to complete the data collection, calculation, motor Intelligent Protection. Connect GPRS module to monitor electric submersible pump state. After analysis by the host computer for analysis of engineering staffSystem uses a flexible C-language programming approach, the functional modular design, improved development efficiency, ease of maintenance and up-grading. To realize data acquisition, processing, motor protection and communi-cations and other tasks of management and scheduling.After been tested, hardware and software system has accurately realized the various functions to meet the needs of users.
