A general decoupling method and system for electromagnetic transient simulation of a VSC are provided. The method includes: determining state equations of equivalent circuits and switch state tables of different VSCs; splitting the state equations, and decoupling and delaying capacitor elements and inductor elements to determine split equations; determining a recurrence relation of a state variable group with respect to a time sequence based on each split equation; obtaining a topological structure of a to-be-simulated VSC, and determining a decoupling model circuit; determining a switch state of the to-be-simulated VSC at a current simulation moment, and constructing a final decoupling model circuit; determining an external port voltage based on the final decoupling model circuit; and updating the state variable group at the current simulation moment based on the external port voltage and the parameters of the decoupling model circuit corresponding to the switch state.

An administrator agent and local worker agents are provided in nodes of a distributed system to support dynamic tracing of runtime data. Trace profiles are associated with the nodes on which the local worker agents reside. The local worker agents monitor the runtime data for an error, and the administrator agent adjusts the trace profile(s) in response to the error(s). The administrator agent sends the adjusted trace profile(s) to the local worker agents, so as to enable trace output data of traces performed by the nodes to be increased or decreased.
