Electricity boards have implemented KVAH billing — lower penalty is applied only when PF is closer to unity.
Maintaining grid power factor during minimum import and fluctuating load is very difficult.
Earlier improvements relied on Passive components which are expensive and inflexible.

New system for captive power plants that maintains grid PF near unity via the TG set connected with the grid.
Much cheaper and more effective than capacitor bank / SVC installations.
Fully automated Grid PF improvement system with complete safety, interlocking and protection.
Works in line with the Generator Capability Curve supplied by OEM — generator reactive power is used in the best possible manner.
Maintains grid power factor during minimum import and fluctuating load to near unity, and improves performance during higher import.
KVAH billing is being implemented in Odisha, Chhattisgarh, UP, Maharashtra and other states — the system is trending nationwide.
Installed in more than 30 plants.

Maintains stability of the power system in critical situations such as sudden loss of a power source or generating unit.
Establishes and monitors the balance of generated and consumed load by shedding low-priority feeders.
Automatic shedding is the only way to prevent sudden frequency drops or frequency collapse after a large disturbance.
Grid MD (maximum demand) control.

System takes grid data, TG generation data and load-shedding feeder data as inputs.
All balancing calculations are performed by the system itself.
Sheds feeders based on priority set by the user — critical loads are preserved, non-critical loads shed first.

Harmonics are currents/voltages at integer multiples of 50Hz that distort the fundamental waveform.
High neutral currents from poorly distributed single-phase loads or high triplen harmonics.
Overheating in conductors, capacitor banks and sensitive electronics.
Failure and tripping of fuses and circuit breakers.
Excessive heating in transformer windings and generators.
Incorrect utility metering — higher bills to consumers.
Spurious tripping of protection circuits.
Failure of commutation circuits in DC/AC drives with SCRs.
Interference with computers and telephones.
Overall inefficiency and accelerated equipment deterioration.

Electrical Transient Analyzer Program — a network modeling and simulation tool used by power system engineers.
Creates an electrical digital twin to analyze power system dynamics, transients and protection.

Active power sharing with Grid-to-TG and TG-to-TG synchronisation even without grid power.
Developed using dedicated Gen-set controllers and Mains controllers.
Controllers communicate via redundant CAN-bus protocol and share automatically during island operation, avoiding unwanted tripping during grid failure.
Built-in load sharing and auto-synchronisation.

If the Grid Breaker opens, TG-1 and TG-2 immediately move to percentage-based sharing.
During island operation, if one generator trips due to process variation, the extra load is shed by priority (critical vs non-critical) per user configuration.
When grid power resumes and parameters are healthy, the system auto-synchronises at a single point — no manual operation required.

AVR problems cause voltage instability, poor reactive power control and generator trips.
Field commissioning, tuning and fault-finding require specialised experience.

Engineering that pays for itself.
