Investments in the automation of the Warsaw power grid are growing

A key element of the country's energy transformation is the creation of a new energy model . This must include adapting electricity grids to new conditions, such as renewable energy generation, storage, and management using smart platforms.

Therefore, distribution system operators (DSOs), who play an important role in this process, are changing their offer and developing services to keep up with the dynamically changing realities of the energy market.

Investments in power grid automation

Decentralizing the energy system, increasing the share of renewable sources, and implementing modern management technologies require innovations that improve its efficiency and flexibility. Therefore, changes are necessary that will enable the introduction of integrated solutions managed through intelligent platforms and IT systems.

Operators are focusing on extensive control and automation. They are implementing solutions that enable near-complete monitoring and assessment of the condition of energy infrastructure and control of its components to ensure its stability and efficiency.

Thanks to these solutions, the company can monitor and analyze various network indicators in real time : voltage, energy flow, and frequency. This allows it to detect and diagnose overloads or outages before they become serious. Stoen Operator employees also have the ability to control energy flow, regulate voltage, and manage network load, for example .

Fault indicators and remotely controlled switchboards

Stoen Operator utilizes fault indicators and remotely controlled switchboards, managed and monitored by SCADA systems, among other technologies. It has also implemented modern technologies in urban infrastructure. An example is the advanced DGA (Dissolved Gases Analysis) monitoring system for 110/15 kV transformers located at five distribution power points.

These devices remotely monitor the presence and concentration of gases dissolved in esters inside transformers and alert in the event of damage.

The company also recently completed pilot tests monitoring partial discharges in medium-voltage cables. The PD Doctor device, which utilizes proprietary technology, enables precise detection of these phenomena at an early stage. The equipment also allows for manual adjustment of the warning level.

When selected values ​​are exceeded, an alarm is sent to the energy emergency service employee, which triggers a quick response and planning of the modernization of the given element.

Thanks to this, the company locates and repairs failures faster, and the duration and frequency of power outages (i.e. key network reliability indicators, SAIDI and SAIFI) remain low.

Stoen Operator supplies electricity to over a million customers in Warsaw and the surrounding area.
