The simulation demonstrates that even though K value is same, the power grid impedance angle and wind farm power factor may also affect the voltage variation which is caused by wind farm.
指出在K值相同时，风电场引起的电压变化还与电网阻抗角和风电场功率因数有关。
Electrochemical performances of different grid alloys, including the performances of corrosion resistance, gassing evolution and the impedance of corrosion layer, were studied systematically.
系统地研究了不同板栅合金的耐腐蚀性、析气性能、表面腐蚀层阻抗等电化学性能。
But for high frequency problem and complex structure, too dense grid of object will lead to dense impedance matrix and many unknown variables, so the computational efficiency will be very low.
但是在处理高频问题和具有精密结构的缝隙时，对目标剖分过密会导致稠密的阻抗矩阵，未知量增加，影响计算的效率。
