Abstract :
This paper presents a numerical method to analyze the complex process of fault synchronizing parallel operation. A set of state-space equations is adopted to calculate the transient current and electromagnetic torque of the process. A new type of high-voltage synchronous generator is introduced for fault synchronizing parallel operation.
