Contract I – laying the foundations: Power Quality Monitoring System (SMJEE)

Completed in December 2012, the first stage covered the design and implementation of a power quality monitoring system at 21 PSE Operator substations. It established a data-transmission system to the Power Quality Monitoring Center, with remote data transmission from measurement devices as a key element.
T4B used proven Swedish UNIPOWER technologies, enabling accurate and reliable monitoring of power-quality parameters such as voltage, frequency, and harmonic distortion.

Contract II – nationwide expansion

Launched in May 2021 (ongoing), the second contract expands the system across 54 PSE facilities nationwide and includes:

• Purchase, installation, and commissioning of 140 Power Quality Analyzers (AJEE) and measurement cabinets,

• Delivery of necessary teletechnical infrastructure (cabling, integration with the PSE network),

• Installation and deployment of software in the Client’s primary and backup Data Processing Centers,

• Providing SMJEE application access for 50 end users.

With the growing share of variable renewables (PV, wind), power-quality management is a pillar of safe, efficient grid operation. T4B provides:

• Monitoring and mitigation of disturbances (voltage fluctuations, harmonics),

• Compensation and stabilization systems,

• Integrated Energy Management Systems (EMS) with forecasting and demand control,

• Energy storage systems ensuring continuity with variable generation.

“Our experience in designing and integrating power-quality monitoring systems lets us deliver technologies that boost efficiency, reduce losses, and increase security of the entire transmission network—not only in Poland, but abroad as well,” says Łukasz Składanowski, T4B Project Manager.

These technologies are increasingly exported—including to African markets, where stable electricity supply is a key development challenge.
