This paper describes a complete implementation of the experimental voltage regulation of a wind energy conversion system using STATCOM. Firstly conventional control technique is used which is proportional plus integral controller. The control technique is performed using a PC computer through a suitable interfacing and opt-isolating facilities. Secondly fuzzy logic controller is facilitated in this scheme to improve the performance of the experimental setup. Several efforts are done to choose the suitable gains of the fuzzy controller to achieve superior performance of the wind system. Experimental results of the system show the effectiveness of the proposed technique in regulating the output voltage. Thanks to the operation of the STATCOM in controlling the reactive power of the system to fix the output voltage at the desired value regardless of the wind speed.
This paper describes a complete implementation of the experimental voltage regulation of a wind energy conversion system using STATCOM. Firstly conventional control technique is used which is proportional plus integral controller. The control technique is performed using a PC computer through IntroductionMoreover, wind power is expected to be economically attractive when the wind speed of the proposed site is considerable for electrical generation and electric energy is not easily available from the grid. Wind system with STATCOM is very reliable because the STATCOM acts as a cushion to take care of variation in wind speed and would always maintain an average voltage equal to the set point. However, in addition to the unsteady nature of wind, another serious problem faced by the isolated power generation is the frequent change in load demands. This may cause large and severe oscillation of power.Several tests are made to validate the system response at different operating conditions. Different choices of the scaling factors of the fuzzy logic controller have been assumed toobtainthe best response of the system. The test results are recorded and plottedfor a wide range in wind speed. Output power, inverter current, inverter voltage, and STATCOM control voltage (Vc) are recorded. In each test change in wind speed, several combination of scaling factors are asummed. Which system is regulated at different wind speed [1,2]. Nevertheless, under the sudden change of load demands and random wind power input, the pitch controller of the wind side able to effectively control the system frequency due to theirs slow response. FACTS devices can be a solution to these problems [3]. They are able to provide rapid active and reactive power compensations to power systems, and therefore can be used to provide voltage support and power flow control, increase transient stability and improve power oscillation damping. Suitably located FACTS devices allow more efficient utilization of existing transmission networks. Among the FACTS family, the shunt FACTS devices such as the STATCOM has been widely used to provide smooth and rapid steady state and transient voltage control at points in the network. In this paper, a STATCOM is added to the power network to provide dynamic voltage control for the wind system, dynamic power flow control for the transmission lines, relieve transmission congestion and improve power oscillation damping.Following sections deals with the experimental tests of the wind system equipped with STATCOM. Proportional plus integral controller schemes are used to improve the voltage regulation and to minimize the voltage fluctuation during variation in wind speed. Several experimental tests are performed to adjust the proportional plus integral gains at optimal operation of the practical system. Each test describe the voltage adjust by injection voltage by STATCOM. In addition, the controlling voltage of the STATCOM is recorded.
