-Unlike traditional thermal power generating units in the uncontrollable nature of its prime mover power wind turbine, which is caused by the variability of the wind speed and uncontrollability. Wind speed condition has an important impact on the performance of the wind power generation system, and also makes wind model to become an important part of the wind power system simulation model. Paper, the characteristics of wind speed changes randomly, on the basis of the wind speed statistical characteristics of self-regressive moving average (ARMA) method to set up wind speed model has a certain power spectral density characteristics. Analysis and validation of the model simulated wind speed sequence, compared with the results of existing simulation program in wind speed model, results show that the proposed ARMA model can effectively generate dynamic analysis and simulation of the wind speed required sequence .

Description: Abstract—If a wind farm is weakly connected to a power grid,
then the voltage of the connection point fluctuates frequently
due to the changeable wind speed. The active and reactive power
of a doubly-fed induction generator (DFIG) can be decoupling
controlled and the grid-side converter (GSC) of a DFIG can also
generate some reactive power by adjusting the power factor,
thus a DFIG can be considered as a reactive power resource to
stabilize the voltage of the connection bus. Platform: |

Description: The permanent magnet synchronous motors (PMSM) are used as servo motor for precise
motion control and are used as generator to generate electrical energy driven by wind energy.
There is large variation in inertia due to varying load and parametric uncertainty in PMSM.
The design objective of this paper is to analytically determine the relative robust stability of
PMSM with parametric uncertainty using Kharitonov theorem and Routh stability criterion.
The conventional integral controller (IC) and two robust internal model controllers (IMCs) are
used for relative robust stability analysis of speed control of PMSM. The frequency domain
performance specifications like gain margin (GM) and phase margin (PM) are taken for
relative robust stability analysis, and the effect of controllers on time domain performance
specifications such as settling time (ST), rise time (RT) and overshoot (OS) is also studied. Platform: |
