Design and application of high-capacity shunt hybrid active power filter

According to the integrated requirements on harmonic elimination and reactive power compensation,the paper considers better filter performances and less cost of active power filter,and then forms a whole set of design methods for high-capacity injection type shunt hybrid active power filter.Its application in a smeltery's 220kV substation can meet the harmonic suppression requirement well and the effect is obvious for both the high performances and low cost.China has few applications of high-capacity shunt hybrid active power filter till now,hence the given parameter design method and engineering experience are useful for applications and research of other active power filter.
