2 NEW GENERATION ELECTRONIC THYRISTOR CONTROLLED PF CORRECTOR SYSTEMS ELECTRONIC PF CORRECTOR SYSTEMS Improved operating efficiency is crucial and topical subject around the world. Reduction of energy costs is regarded worldwide as one of the crucial challenges to all branches of the industry. Reactive energy is chiefly regarded as one of the causes for the consumption of unusable energy and that is why reducing reactive energy usage has traditionally been one of the simplest ways to conserve energy. Today, Conventional Compensation Systems are the most common solution providers to eliminate...

3 Screen Shot 1: Capacitor Activation with Contactor Screen Shot 2: Capacitor Activation with Thyristor As can be observed in Tables 1 and 2, while the active total power is steady (61 kW – 65 kW), total active and reactive power drops significantly to prevent the overloading at mains and transformers. Table 1: Electronic Compensation System is OFF Table 2: Electronic Compensation System is ON COMPARISION MECHANICAL COMPENSATION • Each phase controlled independently enabling the device to handle unbalanced loads at optimum level. • Response time is 20 msec. for fast changing loads • Increased...

4 Separate Correction of Each Phase (EKM) – Capaciti ve an d Inducti ve Correction with 20 msec . Correction Spee d (EKM-EKT) Load unbalances among phases are perfectly eliminated with separate correction of each phase. The number of activated capacitors is limited to the actual requirement at each phase. Capacitive reactive load correction is also maintained at each phase with a similar logic. Added reactor to sixth arm can also be set in motion via thyristor module if inductive kvar is needed.

6 As demonstrated below, while the active power remains stable (81 kW-83 kW), the kVA value diminishes by more than 25% (116 kVA – 84 kVA). Such a significant difference can be explained by as follows; 1. Additional Power Capacity: Generator’s consumed power for reactive energy (over 25%) can be used for active energy (pf corrected from 0.7), so that it will be possible to have more loads with the same generator set. 2. Energy Saving: Since the reactive power is eliminated, the current at mains will decrease at the same rate, which will bring savings on energy usage. 3. More efficient Operation...

7 • Each phase controlled separately to enable the system to handle unbalanced loads at optimum level. • Response time is 20 msec. for fast changing loads • Increased capacitor life with zero current switching • 32 step capacitive and 2 step inductive sensitivity correction with binary logic • No current harmonics with harmonic filters at each of 5 arms • Semiconductor switching increases reliability • Periodic test of capacitors and semiconductors to give prior failure detection • Remote communication and monitoring with RS 485 • Modular construction and easy service • Parallel operation with...
