电容器零序电流解析：稳态项和暂态项

Equation (4) represents the zero-sequence current of the capacitor, which consists of two terms: the first term is the capacitive current of the capacitor that has already been connected, which is a steady-state term; the second term is the transient pulse zero-sequence current generated by the first connection, which is a transient term. This transient current is generated by the connected capacitor and flows through the zero-sequence circuits of the busbar. Equation (3) describes the zero-sequence current distribution of each zero-sequence branch.
