发明名称 METHOD AND APPARATUS FOR CONTROLLING DIRECT-CURRENT VOLTAGE
摘要 The present invention discloses a direct current (DC) voltage control method, including: determining, when it is determined that a DC voltage primary control station loses a DC voltage control function, whether the DC voltage primary control station can communicate with the DC voltage secondary control station, and if yes, sending, by the DC voltage primary control station, information about the DC voltage primary control station losing the DC voltage control function to the at least one DC voltage secondary control station and enabling a DC voltage control function of one DC voltage secondary control station, so as to adjust a DC voltage; before the DC voltage control function of the DC voltage secondary control station is enabled, if the DC voltage exceeds an operation range, enabling, by the at least one DC voltage secondary control station, a DC voltage auxiliary control function, so as to adjust emitted or absorbed active power; and when the DC voltage primary control station cannot communicate with all of or some of the at least one DC voltage secondary control station, and if the DC voltage exceeds the operation range, enabling, by at least one DC voltage secondary control station, a DC voltage auxiliary control function, so as to adjust current emitted or absorbed active power, and determining, according to a policy, one DC voltage secondary control station to enable a DC voltage control function, so as to adjust the DC voltage. The present invention further discloses an apparatus for implementing the method. With the present invention, DC voltage oscillation of a system, which is caused when a DC voltage primary control station stops running, may be reduced:
