Transient Specifications and Reactive Power Compensation Using ShAPF for Non-Linear Load Applications

摘要

In distribution system network the necessity and adoption of non-linear loads is becoming very common in present scenario. Since these loads accounts for the insertion of harmonics in line current, which results in unbalanced voltage and reactive power but their use can not be ignored as we are entering in the era of modernization. Thus it becomes very essential to have a solution to get a healthy system with less disturbance in line current and compensated reactive power. This paper presents design of a transformer less shunt active power filter to improve transient specifications and to get the system more stable with improved power factor. The action of ShAPF is controlled using PID/Fuzzy/ANN controller and the comparison has been made among the results obtained from the simulation model of all three methods.
