In the weak current network, due to the large impedance characteristics of the power grid, the impedance parameters in the line change the key parameters of the rectifier control, affecting the overall performance of the rectifier, which may lead to the unstable output of the rectifier, and the output presents the characteristics of sub-synchronous oscillation. On the basis of not increasing the hardware compensation system, this paper proposes a control strategy that can effectively suppress the sub-synchronous oscillation. Based on the mathematical model, the AC current component of the sub-synchronous oscillation is extracted through the low-frequency filter. After d/q transformation, the d/q current component of the sub-synchronous oscillation is PI closed-loop controlled. The output value of the PI regulator of the subsynchronous oscillation component is decoupled and compensated, and then multiplied by the compensation coefficient to obtain the d/q compensation component of the voltage. The output of the original current inner loop is compensated. A simulation and test results show that the control strategy is effective and feasible, which can suppress sub-synchronous components.
