“…The orientation condition is given by the following relation [1–5]:

({, \begin{matrix} 1em4pt \\ φ_{normals d} = φ_{s} \\ φ_{normals q} = 0 \end{matrix}) false\Rightarrow {\bar{φ}}_{s} = φ_{normals d} + j φ_{normals q} = φ_{s}

Taking into account this condition, the stator current expression is as follows:

{\bar{I}}_{s} = \frac{φ_{s}}{L_{s}} - \frac{L_{normalm}}{L_{normals}} {\bar{I}}_{r}

Assuming that the electric network is balanced, and neglecting the stator resistance, which is a realistic assumption in the case of the high‐power generators, the stator voltage expression will be reduced as follows:

{\bar{V}}_{s} = R_{s} {\bar{I}}_{s} + \frac{d}{normald t} {\overset{false¯}{φ}}_{normals} + j ω_{normals} {\overset{false¯}{φ}}_{normals} = j ω_{normals} φ_{normals} = j V_{normals}

where

V_{s}

is the voltage amplitude.…”

In this study, a new robust sensorless control of doubly-fed induction generator (DFIG) in the complex domain has been investigated. The proposed sensorless control is based on the extended complex Kalman filter (ECKF) and proportionalintegral complex controller. The design of this sensorless control in the complex domain allowed a threefold objective: a decrease in the system's dimension by half, an optimisation in the implementation of the control strategy and a decrease of the CPU computational time. In fact, to obtain the latter, the dimension of the DFIG model involved in this control has been halved, which leads to a reduction in the control's schema. Moreover, all the matrices involved in the ECKF have smaller dimensions than those of the real extended Kalman filter and no matrix inversion is needed because the output of the system is a scalar variable. The proposed sensorless control has been tested experimentally for several operating points, namely: nominal operation, operation under asymmetrical voltage dip and parameter variations. Moreover, the observability of the complex state model has been analysed and the required conditions for the local weak observability have been defined. The experimental results confirm the theoretical study and show a good reliability and a high rotor speed estimation accuracy.

“…Provisions like implementation of droop control [11] through electrical power feedback, use of PI or PID controller in the controls of turbine governor (very common on modern gas turbine models) have effect on the transient stability. Active & reactive power regulation for turbines is nowadays provided through variable universe fuzzy controller (VUFC) [13], PI controllers & Direct Power Control [DPC] [18]. Therefore, modelling has to be carried out accordingly.…”

This article discusses the work carried out in the development, validation and verification of the Turbine/Governor model (GGOV1) in GE Control Systems Toolbox to comprehend the impact of Turbine controls post system transient. Simulation related studies are carried out using the model developed. MATLAB /Simulink has been used as the platform for validating the model. The validated model is replicated in the GE Control System Toolbox , for enhanced grid Simulation related studies. Comparative analysis of results obtained in both platforms with the validated parameters has been accomplished.
