A Discrete 3-Phase ProgrammableSource block is used to generate a 1 pu, 15 degrees positive sequence voltage. At t = 0.05 s the positive sequence voltage is increased to 1.5 pu. At t = 0.1 s an unbalance is introduced by adding a 0.3 pu negative sequence component with a phase of -30 degrees.
The magnitude and phase of the positive-sequence component is evaluated in two diiferent ways: 1) Sequence calculation of phasors using Fourier analysis and
2) abc to dq0 transformation.
Math Function and Trigonometric Function blocks are used to evaluate the magnitude and phase of the positive sequence from the d and q components:
V1 = sqrt(Vd^2 + Vq^2) , Phi1 = atan(Vq/Vd))

网站上关于遗传算法开发可谓工具箱满天飞。可工具箱超级难用。鉴于此，本人自己完全用matlab实现遗传算法解决多背包问题并留了qq。(Web site development on the genetic algorithm toolbox is all over the place. Toolbox can be super hard to use. In view of this, I am not at all with the realization of genetic algorithm matlab knapsack problem solve and stay more than a qq.)
