说明：  采用PSCAD搭建了简化的换流阀不可控充电过程，并模拟了不同故障下的电路状态。(PSCAD is used to build a simplified uncontrolled charging process of the converter valve, and the circuit state under different faults is simulated.)

example for wavelet analysis using pscad.

说明：  有源滤波器，用于过滤负载谐波电流和补偿无功功率，使得输电线路上的电流为基波分量。(Active power filter (APF) is used to filter load harmonic current and compensate reactive power, so that the current on the transmission line is the fundamental component.)

自己搭的电力系统继电保护中的距离保护模型，对理解继电保护的原理很有帮助(Take your own power system relay protection distance protection model for understanding the principles of protection helpful)

说明：  用PQ分解法实现潮流计算，程序已调试，打开即可用，学校课设必备(Realization of Power Flow Calculation by PQ Decomposition Method)

直流电机的闭环控制C语言代码.同行可以多多交流(Closed-loop DC motor control C language code. Peer may be more exchanges)

61850规约2.0版本，英文版本，求过(61850 statute 2.0 61850 statute 2 version, English version, pls permit)

《电力系统稳态分析》第三版，中国电力出版社，书上P95页，例3-4。经过计算机C语言编程，运用牛顿拉夫逊法，把简单的电力系统潮流进行计算。(load calculation)

热电联供系统多能流建模，采用扩展牛顿—拉夫逊算法统一求解的方法进行计算。(The multi-energy flow model of cogeneration system is modeled and calculated by the unified method of extended Newton-Raphson algorithm.)

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.)
