Addressing Circuitous Currents MVDC Power System Protection
Abstract
This proposal suggests a more cognizant breaker coordination control that can determine the presence of circuitous currents so that the additional diodes are not required. A detailed simulation will be createdspecifically to study the problem of circuitous currents in a zonal ship power system. It will consist of port and starboard busses feeding two zones though a set of four power converters and four z-source breakers. Faults will be simulated at various points in the system to determine the effect on system operation. A small scale laboratory system corresponding to the simulation willbe setup. A method for reconfiguration of circuit breakers that identifies circuitous currents willbe developed. To whatever extent possible, the focus will be on autonomous control that can beimplemented on each individual breaker. The control will be validated using the simulation.The reconfiguration method will then be tested on the laboratory setup.
