包钢热电厂锅炉汽包水位自动控制

The Automation Control on Boiler Water Level for Heat Power Plant

文章介绍了一种已实际应用的电厂锅炉汽包水位三冲量串级控制方法。通过理论计算与实际经验相结合总结出的控制策略,有效地解决了电厂锅炉汽包水位变化的滞后及虚假水位现象。完全满足生产控制要求,是一种安全、可靠的控制方法。

This thesis explains a kind of three - dement vaiue cascade control method which is applied in.the power plant to control the water level in the steam boiler. By combining theory caiculation and practicai experience, the control strategy solved the change hysteresis and falsity of the water level. This control method is safe and reliable enough to serve perfectly for the requirement of produce and control.
