Q1: Transmission STATCOM Mobile Advantages
- A: 1.Allows for Project Construction schedules to have expanded windows for construction by eliminating voltage violations • Eliminates mobilization and demobilization of contract resources • Allows for shorter construction schedules • Provides cost savings to ratepayers and stockholders 2.Growing deployment of renewables and retirement of conventional generation in short timeframes creating additional VAR and dynamic stress on electric systems before projects can be implemented to resolve • STATCOM mobile allows opportunity to quickly resolve operating issue while long term solutions are constructed

Q1: Static Synchronous Compensator
- A: 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.
Q1: SVC PLUS
- A: 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
Q1: Characteristic harmonics
- A: 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)
Q1: Odd harmonics and Even harmonics
- A: 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.
Q1: Harmonic order (h)
- A: The ratio of the frequency of a harmonic (fh) to the fundamen- tal (rated) network frequency (f1). (IEV 161-02-19 modified)
Q1: harmonics
- A: The component of the Fourier-series decomposition of a volt- age or current periodic wave. (IEV 161-02-18 modified)
