摘要
针对日益严重的电力谐波问题,开发了一个专用于工业企业的电力谐波分析和滤波器设计软件。该软件基于频域分析的数学方法,在频域中对各次谐波分别进行分析;对应特定次谐波,采用正弦稳态网络的节点分析法进行求解。该软件基于图形界面,能方便地计算系统的谐波分布,扫描计算系统任意节点的阻抗频率特性;软件本身提供各种常用滤波器模型,可准确计算滤波器的性能和额定值。实际算例验证了软件计算结果的准确有效。
Against the increasingly serious power harmonic problem, a power harmonic analysis and filter design software was developed and dedicated for industrial plants. The software uses the mathematical methods based on frequency domain analysis, with which each harmonic is analyzed respectively. To a specific harmonics, the method of node analysis for sinusoidal steady state network was adopted. The software has a graphical interface, which is convenient for computing harmonics distribution. The frequency characteristics of the Thevenin equivalent impedance at any node can be calculated by the frequency scanning method. Further more, the software provides a variety of filter models and can accurately calculate the filter performance and rating. The satisfactory results of practical examples demonstrate the correctness and practicability of software.
