Circutor OPTIM SVGm-200-440 Hybrid Var Compensator

A 200 kvar cabinet combining a static var generator with detuned capacitor steps

The Circutor OPTIM SVGm-200-440 (code RG20F1) is the smallest unit in the OPTIM SVGm range of hybrid var compensators. Each unit combines a static reactive power generator (SVGm) with steps of rejection filters tuned to 189 Hz (p = 7 percent), operated by contactor and controlled by a computer SMART III power factor regulator. Rated 200 kvar at 440 V (182 kvar at the 400 V supply), it is made of one 100 kvar step plus the 100 kvar SVGm.

Circutor presents the hybrid approach as accurate compensation with a high capacity to react to power changes, a high cost-to-effectiveness ratio, and a smaller size than a bank of regulated capacitor steps alone. The SVGm also provides capacitive compensation, which reduces problems in installations with self-supply photovoltaic systems.

OPTIM SVGm-200-440 functions

• Hybrid design: SVGm static reactive power generator plus contactor-operated rejection filter steps
• Rejection filters tuned to 189 Hz (p = 7 percent) for networks with harmonics
• Quick response to the share of load that must be compensated fast
• Capacitive compensation capability for installations with self-supply photovoltaics
• Controlled by a Computer SMART III power factor regulator (current ratio 5/5 A to 9000/5 A)
• Each step individually protected by HRP NH-00 fuses
• Cabinet construction to IEC 61439-2

OPTIM SVGm range (50 Hz)

Choosing a size from the OPTIM SVGm range

The range steps up in 100 kvar increments, from 200 to 800 kvar at 440 V (7 models, 2 to 8 steps). The RG20F1 has the least capacity, so it suits smaller plants or a first stage that can be extended by choosing a larger model. Establish the reactive demand at 400 V (182 kvar for this unit), whether harmonics call for the 7 percent filter, and whether on-site solar generation creates leading power. Provide the load profile or the existing bank rating and we will compare it with the range.

Installation notes

This is a floor-standing cabinet, 627 x 1959 x 804 mm and 261 kg, with an IP20 degree of protection. The datasheet states a working range of -10 to +45 C, humidity to 95 percent without condensation, and altitude to 2000 m, so room cooling and ventilation matter; noise is below 63 dBA. A short-circuit withstand of 40 kA conditional is printed. CT ratios from 5/5 A to 9000/5 A can be used with the regulator, and each step is fuse protected.

Where the OPTIM SVGm-200-440 is used

Circutor lists installations where rejection filters are needed because of harmonics, but where a conventional contactor bank cannot avoid reactive power penalties, installations where part of the compensating power must respond quickly, and sites that add a self-supply PV system. The 45 C maximum working temperature is a constraint for unconditioned rooms, so consider an air-conditioned electrical room.

Selection and installation notes

This cabinet is a heavy floor-standing assembly. Plan the foundation or floor loading, the incomer cable and busbar entry, the clearance around the cabinet for ventilation and the room temperature before ordering. The network data that matter are the supply voltage, the short-circuit level, the harmonic spectrum and the required target power factor. A power quality measurement before ordering helps to confirm the rating, and the commissioning should include setting the regulator targets and recording the harmonic levels.
