本程序应用于fluent数值模拟蒸发相变过程，由于fluent软件内不含所需的蒸发模型的方程，需要加入用户自定义（UDF编程）计算，改程序即为蒸发相变模拟编程。(This procedure is applied to the evaporation phase transition fluent numerical simulation process, since the evaporation model equations contain the desired fluent software necessary to add user-defined (UDF programming) is calculated, that is, change procedures evaporated analog programming a phase change.)

关于20kV的两端柔性直流系统的建模仿真及其分析( Modeling and Simulation of flexible DC system on 20kV and its analysis)

说明：  对于电力系统网络，当其发生小电流接地故障时，分析其特性(For power system network, its characteristics are analyzed when a small current grounding fault occurs)

程序能够完成三相不对称的潮流计算和故障计算(This can complete three-phase power flow calculation and fault calculation)

说明：  improved algorithmto control APF

可用于如单相接地故障的仿真研究，观察考虑电弧影响的波形(It can be used in the simulation research of single-phase grounding fault, and observe the influence of arc)

仿真模型中，通过1000MW(5OOkv, 2kA)的直流输电线路从一个500KV、5000mva、50hz的电力系统EM向另一个345kv10000mva50hz的电力系统Ell输送电力。整流桥和逆变桥均由两个通用6脉冲桥搭建而成。交流滤波器直接接在交流母线上，它包括11次、13次和更高次谐波等单调支路。总共提供600mvar的容量。(In the simulation model, the 1000MW (5OOkv, 2kA) DC transmission line transfers power from one 500KV, 5000MVA, 50Hz power system EM to another 345kv10000mva50hz power system Ell. The rectifier bridge and the invert bridge are all constructed by two general 6 pulse bridges. The AC filter is connected directly to the AC bus, which includes 11 or 13 and higher harmonics. A total capacity of 600mvar is provided.)

一个在1毫秒中断中查询的B码接收,解码程序(IRIG B CODE recieve and decode .)

ASN.1 编码规则：分组编码规则,各种数据类型的ASN.1的编码方式,非常有用,值得一看(ITU-T Recommendation X.690 (2002) | ISO/IEC 8825-1:2002, Information technology –ASN.1 encoding rules:Specification of Packed Encoding Rules (PER))

说明：  有源电力滤波器 绝对可以运行，参数自己可调，PR控制(Active power filter based on PR control)
