摘要： The present invention relates to a power duplication apparatus for an HVDC system and a control method therefor, and the power duplication apparatus for an HVDC system comprises: a first independent power generator receiving first input power so as to generate and output first power; a second independent power generator receiving second input power so as to generate and output the first power; a first power supplier selectively receiving the first power output, respectively, from the first independent power generator and the second independent power generator so as to convert the first power into second power having a smaller size than that of the first power and output the same; a second power supplier for selectively receiving the first power output, respectively, from the first independent power generator and the second independent power generator so as to convert the first power into the second power having a smaller size than that of the first power and output the same; a first HVDC controller for receiving the second power output from the first power supplier so as to activate the same and control an HVDC converter; a second HVDC controller for receiving the second power output from the second power supplier so as to activate the same and control the HVDC converter; and a power monitoring controller for enabling the first power output from the first independent power generator or the second independent power generator, so as to generate the first power having the same size as that of the first reference power if the first power has a size different from that of the first reference power by comparing the sizes of the first power and pre-stored first reference power, to be transferred to the first power supplier and second power supplier.

摘要： The present invention provides a method for operating dual controller which monitors the state of a dual controller to determine whether the dual controller is faulty and enables operation thereof with a controller in a normal state. An operation method of a dual controller according to the present invention dq-converts control command output values of first and second controllers to calculate rates of change in dq conversion values and dq-converts feedback input values, fed back to the first and second controllers, to calculate average rates of change in dq conversion values. When the average rates of change in the dq conversion values for the control command output values and the average rates of change in the dq conversion values for the feedback input values for the respective first and second controllers are identical, the corresponding controller is determined to be in a normal state, and to be in a faulty state otherwise. According to the results of the determination, the controller in the faulty state is set to a standby state and the controller in the normal state is set to an active state.
摘要翻译：本发明提供了一种用于操作双控制器的方法，该双控制器监视双控制器的状态以确定双控制器是否有故障并且使其能够与处于正常状态的控制器一起操作。根据本发明的双控制器的操作方法对第一和第二控制器的控制命令输出值进行dq转换，以计算dq转换值的变化率，并dq转换反馈到第一和第二控制器的反馈输入值，计算dq转换值的平均变化率。当相应的第一和第二控制器的控制命令输出值的dq转换值的平均变化率和反馈输入值的dq转换值的平均变化率相同时，相应的控制器被确定为处于正常状态，否则处于故障状态。根据判断结果，处于故障状态的控制器被设置为待机状态，并且处于正常状态的控制器被设置为激活状态。
