The Plasma Ignition Control System Is Connected With Power Plant

In the power industry, much of the power source of the power factorys are fromthe pulverized coal boiler, pulverized coal boiler ignition and stable combustionprocess are rare rely on heavy fuel oil and other fuel to complete. In today’s increasinglytight energy situation, the plasma ignition system can save the burning fuel for powerplant, greatly saving the operation cost. Such as the ion boiler ignition system has thefollowing features: simple structure, electrode limit of using plasma arc generated bysmall fluctuations, high the generator’s heat efficiency is more high in the industry toadapt to a wide range and high reliability.This paper describes on the basis of the original generator, innovative design, the newplasma boiler fire a simple structure and more convenient, easy to install. Power plantplasma boiler ignition device together with the traditional oil gun ignition device installedpower plant at any time according to the needs of the boiler ignition switch ignition device,in order to ensure the safety of boiler ignition process.Design the new plasma the boiler ignition systems in the power system, the main stru-cture of the continental plates590series DC converter, DC governor for three-phaseth-yristor rectifier.Schneider Twido Series Programmable Logic Controller (hereinafter referred toasPLC) as this boiler ignition system automation and control center, PLC and DC drivescommuni cation control. PLC and power plant Distributed Control System(hereinafter referred to as DCS) taken between the hard wiring for signaltransmission. Use of theTwido Soft software development, the logic control program.From hardware and software to study the the arc stable combustion conditions andrequirements. Take advantage of the current real-time control of the control methodd, tomeet generator steady-state and dynamic quality index. Through the experiment, a comprehensive analysis of the key to the success of the arc,to explore the characteristics of the stability in the system parameters. In the entirerunduring the experiment，the power supply system is good, strong arc flame to verify thefeasibility of the entire system program.
