摘要(Abstract)：

结合扩大单元接线的特点,基于单元接线机组附加调差系数的整定方法,提出一种可以工程化应用的附加调差系数整定方法。以某采用扩大单元接线方式的发电厂为例,应用该整定方法对发电厂2台机组的附加调差系数进行整定,通过建模仿真验证了该整定方法的可行性和有效性。现场运行情况表明,经整定后的参数能够满足机组运行需要。
Firstly, the characteristics of expanded unit connection are analyzed. Based on reactive current compensation coefficient setting method for generators in expanded unit connection, an engineering applicable reactive current compensation coefficient setting method for generators in expanded unit connection is proposed.Then, the method is used in a power plant of two-generator in expanded unit connection to get the reactive current compensation coefficient. The feasibility and effectiveness of the setting method are verified by simulation and modeling. The field operation shows the setting coefficient can meet the need of unit operation.
