ZDDQ Static Synchronous Compensator (STATCOM) solution is a custom designed system to be installed on transmission grids. It provides grid operators with reactive power compensation and improved range of operational voltage with a faster response time and a smaller footprint than traditional SVC solutions.
SVC PLUS combines the benefits of static synchronous compensation (STATCOM) and modular multilevel converter technology with an optimized amount of components. SVC PLUS is the fastest dynamic voltage stabilizer
Those harmonics produced by static converters during theo- retically ideal operation. The characteristic harmonic order of static AC/DC converters is given by h = mp ± 1, where p is the pulse number of the converter and m is any integer. For example, the six-pulse converter circuit has characteristic harmonics with order numbers h = 5, 7, 11, 13,1 7, 19... . (IEC 61642)
Harmonics with odd harmonic order,such as 3rd,5th,7th,9th,...,49th order harmonics, Harmonics with even harmonic order.such as 2nd,4th,6th,8th,...,50th order harmonics.
