A negative order imbalance load treatment method based on Steinmetz theory

Based on Steinmetz's theory, a simple calculation method for the capacity of negative sequence imbalance control device is proposed. The control application methods of negative sequence current method and negative sequence voltage method in the coordinated operation control of multiple master-slave machines at the same station and different control objectives at different stations in practical engineering are built. The on-site treatment method for traction stations is also provided, advocating that users strictly abide by the principle of "whoever pollutes, who treats" to unite and preserve the power grid, and jointly promote the harmonious development of regional power grids.
