需全套CAD图纸 联系Q174320523各专业都有 摘 要 调节系统有全液压式，WOODWARD 机械液压式及由微机控制的电液调节系统等多种调节系统，一般根据参数对系统功能及由自控水平的要求进行合理的选择和配置。 随着电力工业的发展，200MW机组已成为电网的调峰机组，其负荷适应能力及响应速度的快慢便显得越来越重要，过去，国产200MW机组控制普遍采用传统的液压控制系统，此类系统结构复杂，控制精度低，可靠性差，传动速度慢，已远远满足不了电网调度自动化的要求。power industry, the 200 MW machine set has become the charged barbed wire net to adjust the Along with the development of the electric machine set, it carries the ability of adapt and responds to the rate of speed of the speed and then seem to be more and more important, past, the domestic 200 MW machine set controls the traditional liquid of widespread adoption to press to control the system, this kind of system structure complications, the control accuracy is low, the credibility is bad, spreading to move the speed slow, already far far satisfy not the charged barbed wire net adjusts the request of one degree automation.But the electricity liquid regulate the system to be more and more value. Have study appies and pricles of steam turbines .In general the nozzle control is adopted.The openning and closing of the governing and closing of the governing valves are controlled by an oil servomotor via a beam,two spindles and a level system. in govering,have speed control system WOOD505、protection、local control panel 、protection Equipment and so on. Turbines are equipped with safety devices for pressure,live steam pressure,extraction steam pressure vacuum,axial displacement of rotor,and the monitoring devices for speed,vibration,temperation,pressure etc. Along with dispersion continuously raise of the control system technique level, a power station is controled the system by the dispersion of the one type to complete all control mission and is a future development trend.
