电力系统故障仿真计算源码和模型，可以用来仿真电网的单相、两相和三相故障(Source and model of power system fault simulation can be used to the simulation grid single-phase, two-phase and three-phase fault)

说明：  月球软着陆仿真：在停泊轨道上，探测器在脉冲制动的作用下，经霍曼变轨，下降到距月面大约 15 公里的近月点，该近月点就是主制动段的初始制动点。主制动段以下是障碍检测与规避和最终着陆段。在主制动段，由于探测器的初始速度很大(1.692km/s)，所以主制动段制导律设计的主要目的就是高效抵消此速度，将探测器导引到期望的末端状态(Lunar soft landing simulation: in the parking orbit, the probe under the action of pulse braking, through the hohmann change of orbit, to descend to about 15 kilometers from the surface of the moon, the near-moon point is the main braking section of the initial braking point. Following is the main braking section for obstacle detection and avoidance and the final landing section. In the main braking section, since the initial velocity of the detector is very large (1.692km/s), the main purpose of the guidance law design of the main braking section is to effectively offset this velocity and guide the detector to the desired terminal state)

A simple PSNR calculator that might be handy in measuring the PSNR between two frames in a video. Typically used in measuring the distortion when videos are encoded and decoded.
