Compensation Optimization (CO) Siemens PSS SINCAL Optimization and Planning Modules

Compensation Optimization (CO)

The optimized utilization of reactive power compensation has a positive effect on network operation. Typical advantages are:

• Reduction in transported apparent power and loading of network components
• Reduction in system losses
• Improved voltage profile and mitigation of voltage limit violations
• Postponement of otherwise required network reinforcements
• Reduction of costs of reactive power consumption

The module compensation optimization (CO) in PSS®SINCAL offers methods for the optimized usage and placement of reactive power compensation equipment.

Reactive power optimization

A series of load-flow calculations for the entire network determines the required reactive power. In each individual load-flow calculation, a fraction of the reactive power requirement at the transformers is compensated. The reactive power requirement can be inductive or capacitive. The calculation of the reactive power requirement is carried out for selected voltage levels. In the graphical network diagram, shunt reactor or capacitor symbols are depicted at the lower voltage side terminals of transformers for network areas where reactive power is needed to achieve a specified power factor. PSS®SINCAL can also propose standard ratings based on types specified in the equipment data base.

All relevant load flow results (such as the required reactive power, reduction in losses, etc.) can be displayed.

Automatic capacitor placement

This optimization method has the objective to reduce network losses by placing capacitors in the network. PSS®SINCAL can identify optimum locations for capacitor installation offsetting the costs for capacitors and expected savings from reduced losses. Based on costs and savings the return on investment is calculated.

Applications

Independently or simultaneously analyze the impacts of low, medium, and high-voltage networks

Through its modular design, PSS®SINCAL is highly flexible and customizable. It offers a wide variety of analysis functions for the planning, design and operation of power systems, allowing you to simulate and study: power quality, frequency stability, distributed generation interconnection, protection coordination, restoration of supply, economic driven design decisions, and more.
