| In recent years, the continuous development and growth of China’s electric power industry, and increasing high power nonlinear load of the industry impact on the power system. The harmonic pollution is also showing a rising trend. Lack means of reactive power regulation will lead to a lack of power system bus voltage change with the system operating mode and undergoing tremendous changes, caused a lot of power quality problems.The basic principle of the reactive power compensation, analyzes the no adverse impact on power system reactive power, explains the necessity and significance of reactive power compensation, introduces four kinds of commonly used form, reactive power compensation mode, reactive power compensation on the electric energy quality and determine the main role reactive power compensation method. Discusses the domestic lOkV has no major problems in reactive power compensation technology and its solution.Then introduced the SVC three common forms of TCR, TSC and SR, and their advantages and disadvantages are analyzed, analysis of the trigger pulse and the trigger circuit design without power system wiring mode, analyzed according to the power control method of voltage sag and reactive compensation current, analyzes the control strategy of TCR and TSC two a branch, and finally through the system simulation verifies reactive power compensation effect of SVC.Through theoretical analysis and examples of the meaningless and leased by the reactive power compensation of transformer, line loss rate, the power voltage, combined with the actual situation of work, analysis of the transformer power supply line a power plant generated in the reactive power compensation in economic benefits, and the energy saving effect of capacitor compensation on the spot and extension valueThe distribution network reactive compensation is not only an effective measures of saving energy and reducing loss, mature technology, simple, less investment, quick effect, should accelerate the promotion. |
