The invention provides a direct-current power energy area compensation method based on converter station local information. The method comprises the following steps of: judging whether a direct-current power energy area compensation function needs to be started; calculating direct-current power energy compensation quantity; and calculating a direct-current power energy compensation area after an alternating-current fault. The invention aims to improve the frequency and voltage recovery characteristics of an alternating-current system after a fault and do not rely on safety control and coordination control devices of remote measured signals and system layers, the direct-current power compensation quantity and the continuous time of an on-line adjusting system deceleration area can be accurately calculated based on the converter station local information, an oscillation process is inhibited after the alternating-current system on a rectifier side fails seriously, and the stable state recovery of the system is accelerated; and with regard to an alternating-current fault on an inverter side, the frequency and voltage recovery characteristics of the system are improved, and continuous commutation failures are avoided.
