نبذة مختصرة
It is important to have an analytical method to predict the voltage collapse in the power systems, particularly with complex and large power systems. In this thesis, a developed Newton Raphson method is application to find the voltage profile before and after improving voltage. A new method, Field Programmable Gate Array (FPGA) circuit is used to address reactive power compensation as an on-line solution of this problem.
A steady state analysis is applied to study the voltage collapse problem. The model analysis method is used to investigate the stability of the power system. Q-V curves are used to confirm the obtained results by model analysis method and to predict the stability margin or distance to voltage collapse based on reactive power load demand.
The load characteristics are considered in this thesis. Different voltage dependent loads are proposed in order to be used instead of the constant load model. The load is connected to several selected buses. The analysis is performed for two IEEE system; Western System Coordinating Council (WSCC) 3-Machines 9-Bus system
The FPGA can solve this problem as an on –line using reactive power compensation by two Spartan cit3 (XC3S200) designed by xilinx program (using VHDL), first Spartan Cit3 is receive data from computer and second Spartan Cit3 transfer data to sub distribution board connected to the power system .
FPGA circuit can be used in electrical power system by connecting two spartan cit 3. The program moves information from dismal to binary to be Known or readable by the Cit will save if and move it to the system by another that sends information to a sub distribution board connected directly with the power system .
While helps to entrance Reactive power compensation to the system which helps to improve Voltage profile in the electrical system to ensure the continuity of stream energy and not to the instability state arriving at voltage collapse in the electrical powers systems shown in Fig 28
