| Due to a shortage of energy,the renewable energy is gradually being developed and utilized.The wind power, a clean renewable energy with no pollution,is advancing very rapidly. But the problem of the reactive power flow problem restricting the use efficiency of the wind power generation, while safe operation plays a vital role in interconnection.More ever, this is an urgent need to solve the first concern.There are many methods of current reactive power compensation,but for in-depth study of magnetic valve controllable reactor to solve the wind farm reactive power compensation, so far there is still little relevant research literature.This paper analysis the wind power field’s equipment and then selects appropriate reactive power compensation installation.By the brief characteristic analysis of MCR type magnetic control reactor,the writer discovers that the reaction speed is so slow that cant’s satisfy the requirement of the quick speed reactive compensation of wind farm.The improvements based on the MCR type magnetic control reactor were made,and this paper puts forward a theory approach that can react quickly concerning magnetic control reactor.In addition, it suggests the core of the voltage magnetic control reactor of rapid reaction type, winding structure and principle of fast track. What’s more,the paper analyses the steady working process of the reactor and the stable operation parameters,and then the formula of it’s fast track time was given,the stimulation analysis was carried out accordingly.The analysis results indicate that putting charging capacitor is involved in the transient process, can greatly improve the working current of magnetic control reactor dc control current tracking speed from original 0.2 s up to 20 ms,which can meet the tracking time requirements of the reactive power dynamic compensation installation. |
