Research On Online UPS Power Supply Of Oil Field Power Supply System

Computers, communication systems and other major communications equipment in the field plays a very key role. They are normal or alternating current situation can occur obstacles for power electronic components supply reliable, pure. There are a lot of ups and UPS to provide backup AC power supply for electrical equipment load equipment, the performance of the online uninterrupted power supply is relatively stable, for the failure of the communication equipment to provide the power supply. However, controlling power, multiple controllers for analog variables are characteristics of the traditional online uninterruptible power supply, is an extremely complicated, high prices of equipment. Therefore, for the contemporary development, we are more concerned with uninterruptible power supply of high quality and high efficiency.This paper introduces a drive module M57959 L produced by Mitsubishi Co IGBT based online power ups. Using silico computer of high computing capability and specially used for control of the region to abundant external devices, the on-line type uninterrupted power supply pulse width modulation special control chip and its peripheral circuit and digital control of the central processor functions to a silicon chip, which can be as much as possible components of the leaves contained in a circuit chip, greatly reduces the cost. The whole power supply uninterrupted use of pulse width modulation control technology, including the generation of PWM wave, PWM rectifier technology, SPWM inverter technology etc..Based on the latest achievements in uninterrupted power supply for the research of high power online uninterruptible power supply, design the online uninterruptible power supply system, from the part of the circuit to the system structure, the regularity of the system work on a very detailed analysis, build the system model by using simulation software simulation,the simulation results verify the effectiveness of the system.
