North of Norway has extremely good conditions for wind power generation. As the existing main grid will not be able to integrate all the wind parks, the alternative to build a new corridor with multi-terminal HVDC Light North of Norway to Middle of Norway, is under study. HVDC Light is more and more concerned recently to improve power system stability due to its supreme controllability. The thesis will be directed towards investigating the possible problems to be encountered in an HVDC Light installation. A platform for the control of HVDC Light based on the vector control principle will be first established. With a good understanding of this control platform, the model will then be tested under several circuit conditions, to test the capability and robustness of the controller to handle these situations.

基天子matlab的双缝干涉从单缝(线光源)发出的单色光射到与之平行的双缝上，即可在双缝屏后获得来自双缝(相干光源)的两束相干光在空间叠加，用光屏承接后可获得干涉图样(在一定范围内出现等间隔明暗相间的平行干涉条纹；用白光做实验则可获得彩色干涉图样)．如果能在计算机上模拟出来.对(Matlab-based emperor s double-slit interference from a single slit (line source) the issue of parallel monochromatic light reach the double-slit can be in the double-slit screen was from the double-slit (coherent light source) of two coherent light beam in the space superimposed with光屏available to undertake after the interference pattern (in a certain range interval appears parallel white light interference fringes experiments using white light interference pattern, they can get color). If we can come out on the computer simulation. On)
