What distinguishes a JJA PROGRESS PFC system?
We execute a follow-up compensation on the basis of networked high-power synchronous motors. We grant a simple regulation structure, a fast response of the system to the demand of reactive power and a reduced need for frequent switching the capacitors on and off. The system uses both the available sources of reactive power of the facility and the equipment built by JJA PROGRESS.
Our system has a tree structure with a central controller responsible for the fundamental control over the compensation process. The local compensators are active in case of loss of remote control, they locally control the process, according to the programmed characteristics.
The advantages of the PROGRESS PFC system
• It’s a verified and reliable solution for a follow-up PFC system working in the heavy industry since 1999
• The investor is not charged with fees for exceeding tgφ and reactive power consumption.
• Full visualization of the system and the electricity network.
• Access to the recorded value of performance of the system and event log.
• The system is completely maintenance free.

Main elements of the system
• Central computer – identifies the current configuration of the 6 kV distribution network. Controls the operation of the system by communicating via an Ethernet network, power analyzers on the input terminals, capacitor banks and synchronous motors reactive power regulators (RPR).
• Excitation circuits of synchronous motors – with high speed RPR systems allow continuous adjustment of reactive power in the network.
• Thyristor exciters – equipped with a RPR software module form a complete block attached to the synchronous motor.
• Graded 6 kV capacitor banks with protective chokes – cover shortages of reactive capacitive power.
• Passive 6 kV higher harmonic filters – limit the adverse effects of the higher harmonic currents on the system.
• Communication system based on a cable/fiber-optic or radio Ethernet network – connects all elements of the system.
• Visualization system – provides a preview of engines, capacitor banks and higher harmonic filters. The visualization system may include any devices that are not yet part of the RPR. Data from a working system and all annexations made in the 6 kV network are recorded and archived.
