一种提高电力推进系统静态稳定性的算法

摘要

In the integrated power system ,the electrical propulsion system generally runs in the mode of constant power and presents negative characteristics .It seriously impacts IPS′s stability .Tradi-tional measure such as adding bus capacitance can improve its stability ,however ,this has the disad-vantage in that very large physical size ,weight and low economy .A DC link stabilizing control algo-rithm is proposed by the research of traditional propulsion driver control method .The principle and performance of the control algorithm are analyzed and simulated .The results show that the negative impedance effect of the propulsion system is dramatically diminished and the positive damper of IPS is provided sufficiently by selecting proper control parameters .%通过对推进变频器传统控制算法的研究，提出了一种直流母线稳定控制算法，并对该算法的工作原理、控制性能等进行了分析和仿真验证。结果表明：通过选择适当的控制参数，该算法在推进系统全工况范围内均可以显著削弱推进系统的负阻特性，使综合电力系统在全工况范围内都具有正阻尼，提高了整个系统的静态稳定性。
