TSC Dynamic Reactive Power Compensation System

Product Overview

The Winzele TSC Dynamic Reactive Power Compensation System is designed for electrical networks with rapidly changing reactive power demand. It improves power factor by connecting or disconnecting capacitor steps through thyristor switching devices, providing fast, contactless operation without the mechanical wear associated with conventional contactor switching.

The controller continuously monitors power factor and reactive power demand, then switches the required capacitor steps to match the load. Series detuned reactors are supplied as standard in the compensation branches. A 7% or 14% reactor ratio is selected according to the system harmonic conditions and project requirements. This configuration helps suppress harmonic amplification, reduce resonance risk, protect the capacitors from excessive harmonic stress, and improve long-term operating reliability.

The TSC system is intended for dynamic reactive power compensation and harmonic-resilient capacitor operation. It does not replace an active harmonic filter where active harmonic current cancellation is required.

System Configuration

A typical TSC system includes a reactive power controller, thyristor switching modules, capacitor steps, standard series detuned reactors, protective devices, and a cabinet cooling arrangement. The number and capacity of the steps are configured according to the site load profile and compensation target.

Key Features

Fast Thyristor Switching

Contactless switching supports frequent step operation and responds quickly to changing reactive power demand.

Standard 7% / 14% Detuned Reactors

Series detuned reactors are standard rather than optional. The reactor ratio is selected according to the harmonic spectrum and system conditions to suppress harmonic amplification and reduce resonance risk.

Dynamic Power Factor Correction

The controller monitors reactive demand and automatically switches the required capacitor steps to maintain the project power factor target.

Improved Capacitor Protection

Detuned branches reduce harmonic stress on the capacitors, while project-specific protection helps support stable, reliable operation.

Project-Specific Step Configuration

Total compensation capacity, step size, number of steps, cabinet arrangement, and cooling are matched to the electrical system and load profile.

Technical Parameters

Final ratings and configuration are determined from the site electrical data, load variation, target power factor, and harmonic conditions.

• Industrial plants with rapidly changing reactive power demand
• Welding equipment, presses, cranes, hoists, and other intermittent loads
