Abstract: Abstract:The data identification function of smart substation was introduced. The collected panoramic data, such as the bus power balance, the uniformity of paralleled bus voltages and the balance of each side power of the transformer, were detected. The data were analyzed and arranged to identify bad data. The detect result shows that the data identification function can meet the actual needs of integrated monitoring of the smart substation.
