摘要(Abstract)：

龙政直流工程的交流滤波器保护装置是ABB在2003年供货的非标准化产品，需要在改造后实现龙政直流工程交流滤波器过负荷保护的标准化。通过分析龙政直流工程改造前交流滤波器过负荷保护和标准化交流滤波器过负荷保护的保护架构、保护原理、保护定值，指出了两者在保护架构、趋肤效应系数的实现方法、保护原理的实现方法、保护定值的表现形式上存在的差异，提出了交流滤波器过负荷保护标准化的改造方法。最后，试验验证了标准化改造后的交流滤波器过负荷保护能够满足工程的要求。
The AC filter protection devices used in the Longquan-Zhengping HVDC transmission project are non-standardized products supplied by ABB in 2003. The AC filter overload protection for the project must be standardized through renovation. Through analysis of the protection architectures, protection principles, and protection settings of the unrenovated AC filter overload protection and the standardized AC filter overload protection, the differences between them in the protection architectures, implementation methods of skin effect coefficients, implementation methods of protection principle, and the expression form of protection settings are expounded. Moreover, the renovation method for standardizing AC filter overload protection is proposed. Finally, it is verified that the standardized AC filter overload protection can meet the demands of the project.
