Conventional Automatic Power Factor Correction Systems (APFC) which were commonly installed in majority of installations to improve power factor till few years back. These systems are having severe limitations in installations with dynamic load changes, sensitive electronic loads and harmonic generating loads.
Not only conventional APFC are ill-equipped to compensate these types of loads but at a same time generate further operational problems in network by aggravating already poor power quality conditions. This in turn drastically reduces the life span of APFC equipment itself. Repeated investment in solving operational issues and repairing APFC panel becomes regular features of such installations.
Realizing this problem many years back we started offering static solutions for Power Factor Correction. Result is Stat of Art Dynamic Thyristor Switched Activcomp System which offers Dynamic Compensation of Power Factor in Real Time. It is Real Time System where in capacitors are connected and dis-connected in the network at zero current crossing through Thyristor switches. This smooth connection and dis-connection avoids the transients effect typically created by Contactors Switched APFC Systems. Additionaly this system is used for harmonic filtration through tuned and detuned reactor as per system designed.
Activcomp System offers Real Time and Efficient Reactive Power Compensation for fast variable loads, sensitive loads, unbalanced loads, normal loads with moderate to high harmonics. It has Dual Power Factor setting suitable for reactive power compensation on Utility supply and DG supply.
Industrial Applications of Active Comp:
Welding Load:
Welding loads are difficult to compensation because of very high level of fluctuation and consumption of Reactive Power. Because of very high variation of current large voltage fluctuation is induced in these networks. These voltage dips not only reduce the welding quality but also create voltage flickering in the network. Activcomp System because of fast and complete compensation largely reduces these negative effects associated with welding loads.
Varying Loads:
Activcomp is the most appropriate solution for industries having large nos. of VFD’s and other harmonic generating loads.
HealthCare:
Normal APFC Panel with or without harmonic block reactors can cause irreparable damage to sensitive medical equipment. Activcomp System is the only suitable system for power factor correction and harmonic filtration for hospitals and other related loads.
Data Centres/ Shopping Malls/Hotels/ Office Buidings:
Most of these modern networks involve installation of large nos. of computer loads, UPS, office automation loads, energy saving lighting, elevators, VFD’s in HVAC and other areas. Normal APFC equipment can generate lot of operational problems resulting in new sense and maintenance issues. Activcomp is the most viable solution for such installations.
