摘要
通过理论计算并结合现场测试,给出了UNITROL F型励磁调节器的准确模型,并提供了硬负反馈系数和瞬时顶值励磁电流限制倍数的计算公式。通过某电厂300MW机组的仿真分析表明,该模型能真实反映该型励磁调节器的动作特性。
Through theoretical calculation with tests on-site, the paper gives the mathematics model of UNITROL F AVR (automatic voltage regulator), and provides calculation formula of rigid negative feedback coefficient and instantaneous excitation ceiling current limit ratio. By simulation analysis of one 300MW unit, it presents that the model can reflect the act characteristic of this automatic voltage regulator.
