Active Power Filter (APF)
APF Principle
Delta's PQC Series APF is connected in parallel with non-linear
loads, and uses one set of current transformers (CT) to detect the
load current.
Features And Benefits
-
Multifunctional: Harmonic, reactive power and imbalance
compensation
-
Harmonic Elimination Range: 2nd~50th order (Selectable)
-
High harmonic filtering rate: Up to 98%
-
Excellent reactive compensation: High speed, Precise
(-0.99 ≤ PF ≤ 0.99), Step-less, Bi-directional (capacitive and
inductance) compensation
-
Excellent imbalance correction: Both negative and zero sequence,
mitigates neutral current
-
Wide input voltage & frequency range, adapts to tough electrical
environments
-
Complete protection: Grid Over/Under voltage, APF over current,
over temperature, and more. All faults are recorded in the event
log, which is convenient for failure analysis
Static Var Generator (SVG)
SVG Principle
The principle of the SVG is very similar to that of Active Power
Filter, as demonstrated in the picture below.
Features And Benefits
-
Multifunctional: Reactive power, imbalance and part of Harmonic
compensation
-
Excellent reactive compensation: High speed, Precise
(-0.99 ≤ Cosφ ≤ 0.99), Step-less, Bi-directional (capacitive and
inductance) compensation
-
Excellent imbalance correction: Both negative and zero sequence,
mitigates neutral current
-
Harmonic Elimination Range: 2nd~25th order (Selectable)
-
Harmonic current capacity: 20% of rated current, 100 kvar SVG
can output 30A H2-H25 harmonic compensation current
-
Wide input voltage & frequency range, adapts to tough electrical
environment
-
Complete protection: Grid over/under voltage, SVG over current,
over temperature, and others. All faults recorded in event log,
convenient for failure analysis
REG2000 Series
A traditional drive system used for inertia load work generally
performs rapid deceleration, braking and positioning. When its motor
is in generator mode it produces large amounts of regenerative energy
that must be consumed to maintain a stable DC bus voltage and safe
operation. The traditional method to solve the regenerative energy
problem is to install a brake resistor.
Delta's REG2000 series is capable of collecting and converting your
system's regenerative energy into reusable electricity for the
ultimate in energy savings. The installation process is as simple as
installing a brake resistor, but with only half the size and better
efficiency.
