摘要
为分析电气弹簧(ES)关键负载电压稳定的影响因素,在分析ES工作原理的基础上,借助数学推导研究了非关键负载电阻、输电线阻抗、LC滤波器中电容/电感、电网频率对关键负载电压稳定的影响,并利用MATLAB/Simulink进行了仿真分析。仿真结果表明:当非关键负载电阻、输电线阻抗、LC滤波器中电容增加时,ES能抑制的电压波动范围先增大后减小;当LC滤波器中电感增加时,ES能抑制的电压波动范围随之增大;当电网频率增加时,ES能抑制的电压波动范围逐渐减小。
To study the influencing factors for stabilizing voltage on critical loads of an electric spring ES,the principle of（ES）is analyzed.By mathematical derivation,the effects of non-critical resistance load,impedance of the power line,capacitance/inductance in the LCfilter,and frequency of the power grid on the voltage stability of critical load are studied.MATLAB/Simulink was used in the analysis.The results show that,with increase of non-critical load resistance,impedance of the transmission line and capacitance of the LCfilter,the range of voltage fluctuation that ES can suppress increases first,and then decreases.With the increase of inductance of LCfilter,the range of voltage fluctuation that ES can suppress increases.As the frequency of the power grid increases,the range of voltage fluctuation that ES can suppress gradually decreases.
