An array of permalloy core solenoids is micromachined as microactuators on (100) silicon wafer. Then anisotropic etching of silicon in KOH solution forms the U-grooves beside the microactuators. The micromachining difficulties from the coexistence of 3-D MEMS devices and deep grooves on chip are overcome successfully. Then two fibers and permalloy piece are assembled onto the wafer together with the microstructures finishing the prototype of the new type MEMS VOA. Third, the inductance, resistance and Q value of the microfabricated solenoids are measured in the frequency range of 1-40 MHz.

It also becomes more difficult to model and simulate power grid. Traditional"Quasi-stationary"phase models can't be used for studying electromagnetic transient phenomena; on the other hand, the EMTP models can be used to analyze the electromagnetic transient accurately, but for the limitation of the step size, it can't be used to simulate the large network with a high speed.

这对电力系统的建模和仿真提出了更高的要求，传统的机电暂态模型由于建立在&准稳态&假设基础之上，因此不能用来仿真变化迅速的电磁暂态过程；而电磁暂态模型，虽然能准确反映电磁暂态过程，但由于仿真步长很小，仿真速度受到限制，不适合用来仿真大型电力系统。
