摘要:
给出三角形接法三相自激异步发电机为单相负载供电时系统的连接方式,通过对系统中 独立节点电量关系的推导,将发电机基值频率下的正序和负序等值电路通过简单的阻抗元件连接,构成合成等值电路。根据 Kirchhoff 定律,以合成等值电路中回路阻抗模值为零作为系统稳态运行的条件和分析计算的基础。采用优化方法计算了不同电容组合下系统的负载电压,求取了负载电压一定时电机所需并联的电容组合,并根据不同稳压电容组合下系统的负序电流所占比重求得最佳平衡状态下的稳压电容值。计算值与实验值相互吻合,验证了该分析方法的有效性和准确性。
Abstract:
The circuit of a delta-connected three-j^hase self-excited induction generator supplying for a single-phase load was illustrated. Based on the boundary conditions of electric quantities in each node,the positive and negative sequence circuits reduced in base value of frequency were connected togetiier as the combined equivalent circuit. According to Kirchhoff ’ s Law,the loop impedance of t!ie combined e-quivalent circuit is supposed to be zero,which is regarded as the condition and basement for steady state analysis. Optimum metiiod was adopted in programming to calculate load voltages under diferent capaci-or combinations and the proper combinations for a given load voltage. The best combination for the most balanced operation witii the lowest ratio of negative sequence current was calculated. The calculated results are in good agreement wit!i experiment data,which verified the validity and accuracy of t!iis analysis method.
