Abstract

Disclosed are an apparatus and a method for correcting data through system analysis for each period in the field of an energy management system (EMS). An apparatus for correcting acquired data includes a topology processing (TP) unit and at least one system analyzing unit. The TP unit acquires data including circuit breaker information from a supervisory control and data acquisition (SCADA) system. The at least one system analyzing unit stores data for performing state estimation with respect to the data output from the TP unit, and processes the stored data according to a predetermined period. In the apparatus, the system analyzing unit is classified into at least one data processing group according to the data processing period.

Claims

1. An apparatus for correcting acquired data, the apparatus comprising:

a topology processing (TP) unit configured to acquire data including circuit breaker information from a supervisory control and data acquisition (SCADA) system; and

at least one system analyzing unit configured to store data for performing state estimation with respect to the data output from the TP unit, and process the stored data according to a predetermined period,

wherein the system analyzing unit is classified into at least one data processing group according to the data processing period.

2. The apparatus of claim 1, wherein the data processing group includes:

a state estimation (ES) unit configured to store the data output from the TP unit according to a data processing period; and

at least one data processing unit configured to process the data stored in the ES unit according to a data processing period of a predetermined data processing group.

3. The apparatus of claim 1, wherein the data processing units having the same data processing period are connected in series to the ES units, and the at least one system analyzing unit is connected in parallel to the TP unit.

4. The apparatus of claim 1, wherein, if corresponding data is output to the data processing unit as a data processing period arrives, the data stored in the ES unit are renewed as the data input from the TP unit.
