“…The diesel engine comprises of IC engine and governor. The operation of IC engine has been already discussed in section 1.2 The governor has two parts mainly, speed controller and actuator [14], [7]. The governor holds on the steady speed all through the working of diesel engine.…”

“…The reference value of the fuel input has been adjusted by the output of the frequency droop. The modeling of speed governor system and that of actuator has been described [14] with the help of second-order transfer functions. The important parameter of a diesel engine is its delay time T D which makes a delay in performance.…”

This paper describes closed loop control of Diesel Generator (DG) supplying power to a Base Transceiver (BTS) load of a telecommunication tower, which is DC in nature. Detail modeling of Diesel Generator set has been presented.. The stability analysis of governor and excitation system has been carried out in frequency domain. When DG source is connected to the BTS load bus through bridge rectifier, the output waveform distorted due to high odd harmonics content. To solve this problem a unity power factor rectifier has been designed. For the control operation of this UPFC rectifier, double loop mode control method has been used and results are presented. The complete system has been simulated in MATLAB-SIMULINK environment.

“…The DE and electronic speed governor block diagrams are typical of those found in the literature. [4][5][6][7][8][9][10][11][12][13][14][15] (See Fig. 4) The PID type speed controller integrates the error in shaft angular velocity and forwards the resulting signal to the second-order actuator model introduced by Yeager et al [15].…”

Isolated hybrid wind microgrids operate within three distinct modes, depending on the wind resources and the consumer grid demand: diesel-only (DO), wind-diesel (WD) and wind-only (WO). Few successful systems have been shown to consistently and smoothly transition between wind-diesel and wind-only modes. The University of Alaska – Fairbanks Alaska Center for Energy and Power (ACEP) has constructed a full scale test bed of such a system in order to evaluate technologies that facilitate this transition. The test bed is similar in design to the NREL Power Systems Integration Laboratory (PSIL) and sized to represent a typical off-grid community. The objective of the present work is to model the ACEP test bed in DO and WD modes using MATLAB™ SIMULINK© and then validate the model with actual full-scale laboratory measurements. As will be shown, the frequency responses are grouped into three classifications based on their behavior. The model is shown to be successful in describing the frequency response of relatively small (0.15 per unit) steps in load. Modifications to the excitation system model are discussed which could improve the accuracy for larger steps in load. The ACEP test bed and associated SIMULINK© model are to be used in future work to support investigating WO operation.

“…A generator is a machine that transforms mechanical energy into electric power. Operation of electric power system involves excitation of the current of synchronous generator which is the main source of reactive power [13]. Prime movers such as engines and turbines convert thermal or hydraulic energy into mechanical power.…”

This paper presents the failure and repair simulation for electric power house with N Turboalternator, where N may be up to 32. The program employs a pseudo-random number generator for individual power plant that can be described by exponential probability density functions. The resulting sequences of failure and repair events are then combined for the plants to give scenarios for different time horizons. The implementation in Excel ®-VBA includes an appropriately designed userform containing the macro Active-X control for input of relevant information. The result shows that as the number of samples increased the behavior of the random events better represented the desired form with a correlation of almost 99% for 25 trials. This corresponds to a confidence interval of better than 95% and hence should be used as the median for practical applications. The results were tested and the distributions of the events were found to be close approximation of the target exponential distributions.
