svpwm is being implemented using matlab simulation blocks

说明：  在前面1维FDTD的基础上给出了2维的FDTD程序。可以帮助我们解决比如波导，光纤中的电磁场计算问题。尤其是给出了边界条件的设置方法。(in front of a peacekeeping FDTD given on the basis of two-dimensional FDTD procedures. We can help solve such as waveguides, optical fiber of electromagnetic computation. In particular, given the boundary conditions be set.)

对大量的数据通过合理的方法按照一定的特性进行合理的分类，只需要输入原数据文件即可。(cluster analysis)

说明：  负荷频率控制（LFC）是调整系统的频率达到额定值（如50HZ）或/和维持区域联络线交换功率为计划值。频率稳定是电力系统电能质量的一个重要指标。负荷的任意突然变化都有可能导致系统间联络线交换功率的偏差及系统频率的波动。因此，为保证电能质量，需要一个负荷频率控制(load frequency control,LFC)系统，该系统的目的是将系统频率维持在标称值并且尽可能使控制区域之间的未计划的联络线交换功率最小。(Load frequency control (LFC) is to adjust the frequency of the system to reach the rated value (such as 50 Hz) or / and maintain the exchange power of the regional tie line to the planned value. Frequency stability is an important index of power quality in power system. Any sudden change of load may lead to the deviation of power exchange between tie lines and the fluctuation of system frequency. Therefore, in order to ensure the power quality, a load frequency control (LFC) system is needed. The purpose of the system is to maintain the system frequency at the nominal value and minimize the unplanned tie line exchange power between the control areas.)
