mimo中的功率控制算法--注水算法与原程序（全）(mimo algorithm waterfill)

说明：  本程序是暂态稳定分析程序，3机9节点模型，对其在pt时刻7号节点发生三相短路故障，并在ct时刻将故障切除进行仿真，最后绘出2号和1号发电机的功角差与时间的关系曲线。发电机模型采用三阶模型，忽略阻尼，电枢电阻取为零；励磁系统仅有量测和放大环节，忽略反馈和电压调节器；负荷采用恒定阻抗负荷。(This program is a transient stability analysis program, three machine nine node model, which has three-phase short circuit fault on node 7 at Pt time, and cut off the fault at CT time for simulation, and finally draw the relationship curve between power angle difference and time of generator 2 and 1. The generator model adopts the third-order model, neglecting the damping and taking the armature resistance as zero; the excitation system only has the measurement and amplification links, neglecting the feedback and voltage regulator; the load adopts the constant impedance load.)

雷达数据显示与分析，包括雷达P显和E显两种方式，同时还可设置雷达量程、指定目标航迹数据显示等，该代码实用，值得参考。(Radar data and analysis, including radar and E P were significantly in two ways, but can also set the radar range, specify the target track data display, the code useful as reference.)
