The effects of load frequency control (LFC) of interconnected distribution power system in tie-line substation area load –frequency stability and the frequency respond at distribution generator (DG) are very important for interconnected control power system of tie-line area. The generating power system of solar farm and wind turbine which have interconnected distribution power system in tie-line substation area were tested using 3 simulation parameters: non-controller Automatic Voltage Regulator (AVR) and with Pl Controller. The results showed that there were 3 types of load and frequency changing in the interconnected area: load changed 0.02 p.u. had frequency of load changed 0.025 Hz and large disturbance. Comparisons of load-frequency to respond for steady state the time respond was 7.9 seconds for non-controller 5.4 seconds for AVR and 1.7 seconds for under controlled system at 0.1 p.u using Pl controller. Therefore the Pl controller has better efficiency than non-controller about 31 % and AVR about 16%. It can be concluded that the interconnected distribution power system in tie-line substation area controlling for storage for connected grid had better efficiency and optimization of generating power from renewable solar farm and wind turbine which have interconnected distribution power system in the nearby are balance of controlling of the original system.

This research project presents about wind turbine simulation for connected single phase grid system using hysteresis current control technique to generate PWM signals for controlling a single-phase voltage source inverter. The simulation system presented here uses the program. MATLAB/Simulink in the simulation of the wind turbine connected to the shaft of a three-phase permanent magnet generator is produced by alternating current through the full bridge rectifier circuit. Then the power supply is applied to the single-phase inverter circuit which is connected to the single-phase autotransformer to power transfer to the single-phase grid system. The simulation results confirm the validity of the proposed system with satisfaction under various conditions.

This article presents the application of the constant Volts per Hertz control to control a three phase induction motor has torque and speed characteristics similar to wind turbine. Due to this method is not complicated and does not require the parameters of motor. As a result the accuracy of control is independent of variation of the parameters of motor. Furthermore the equation for compensate the difference between the moment of inertia of wind turbine and motor which is consistent with the mentioned control method is proposed. In order to make the dynamic responses of the wind turbine simulator similar to the wind turbine and to overcome the problems of noise amplification from differentiation that leads to instability of the system. The simulation results in Matlab/Simulink program show that the proposed wind turbine simulator can imitate the wind turbine accurately both in dynamic and steady state conditions

This research studies designing building and set up a wind turbine that produce the electric current for decrease the contamination that is poisonous be that know that source of electric energy majority production uses the principle burns fuel is a principle which the way aforementioned is building contamination is poisonous moreover still have the prediction from a scientist arrives at crude oil amount that is will down in the future in now a scientist and an engineer differs to are bound for seek the power resource pays back fuel by consider good environment with therefore in this our project has done work education of a wind mill will by have electric power size about 200 watt the religious routine by a wind mill does feeling numb electric charge that wind speed about 3 – 17 the meter builds [ wasp ] second wind topmost speed that can do feeling numb electricity about 17 the meter builds [wasp] second therefore in installation wind mill will should consider the area to will set up that is appropriate must is place where has wind speed shares 5 – 6 the meter builds [ wasp ] second by a wind mill will begin feeling numb electric charge will do feeling numb electric charge keeps in battery12V (12V/100Ah x 2 child sizes are) by feeling numb electric charge will have control feeling numb electric charge when there are 3-17 wind meter speeds build [wasp] second but when there is wind speed abounds 17 more the meter builds [wasp] second the group controls feeling numb electric charge will cut the circuit goes out for protect the equipment within of wind mill group.

This paper presents how to design and build electrical protection equipment to apply for a wind turbine generator system which is modeled on low voltage 3 phase 380 volts system. This electrical equipment acts as a switch to open-close an electrical circuit to prevent an electrical system as well as equipments or devices in the system. It will open the circuit quickly and decrease the contact arcing of a circuit breaker. The implementation of power electronic properties is used instead of mechanical parts which is called “Solid-State Beaker”. This article presents a method of solid-state breaker simulation on the mathematical analysis via MATLAB/ Simulink program in the cases of fault occurring in an electrical system. The simulation is used as a comparison when it is brought into the system. The fault voltage is detected by RMS Method which is implemented in LAB View program. The detection signal will be sent to the solid-state breaker and order it to cut off all three lines simultaneously to confirm the efficient running of solid- state breaker. But this paper has not yet considered the effect of Harmonic.
