四机两区算例(4机2区算例),与昆德(Kunder)书中参数一致，包含详细的发电机模型，算例在PSCAD4.2中可以运行，是学习PSCAD难得的资料。(The four-machine two-zone example (4-plane 2-zone example) is consistent with the parameters in Kunder s book, including detailed generator model. The example can be run in PSCAD4.2, which is a rare learning material for PSCAD.)

自己编的测井数据处理软件，用于处理测井数据，有例子(Own series of logging data processing software for processing log data, there are examples)

三电平箝位二极管采用空间矢量调制能够解决现有的SPWM调制中点电压不平衡的问题(Space vector modulation of three-level clamped diode can solve the problem of unbalanced neutral-point voltage in SPWM modulation)

本例程通过matlab提供的simulink水轮机程序，做了改动，调整了部分参数，并且增加了借阅，模仿水轮发电机组一次调频过程，值得借鉴(Through the Simulink turbine program provided by matlab, the routine has been changed, some parameters have been adjusted, and borrowing has been added to imitate the primary frequency regulation process of the hydro-generator set. It is worth learning from.)
