T80控制器在孤网运行中的应用

Application of T80Controller in the Isolated Net Running

为保证孤网系统的稳定运行,确保当机组发生甩负荷时,不影响大电网的正常运作,在分析孤网运行特点的基础上,将T80控制器应用其中。现场运行结果表明:机组甩负荷时,T80能快速调节执行机构,有效抑制转速飞升,使网频控制在50.0±0.5Hz范围内。

For purpose of ensuring steady operation of the isolated net running and influencing no normal running of the bulk power system while a load shedding appears in the unit,basing on analyzing characteristics of the isolated net running,T80 controller was applied to the grid to show that,when a load shedding happens,T80 controller can regulate the actuator quickly and effectively suppress the rise of rotational speed so that the net frequency can be controlled within 50.0±0.5Hz.
