SINAMICS PCS

The transition of power grids to accommodate the increasing decentralized infeed of renewable sources is posing new challenges for our industry customers. How can load peaks be handled effectively? How can the procurement costs resulting from the use of battery storage systems be reduced over the long term? How can fluctuations in voltage quality be brought under control? And how can they improve the energy efficiency of their own power distribution system? Such questions are exactly why we developed the new SINAMICS PCS (Power Conversion System) grid-converter, as the right choice with minimal efforts for configuration and integration in industrial and public power grids.

Benefits at a glance

Sophisticated overall solution

The challenges are clear, as is the path to their solution: Battery storage systems can help industrial enterprises efficiently solve local problems in their power grids. In addition, they can balance the amount of energy purchased and allow the storage of your own renewable energy generation unit.
Icon rugged

Rugged and reliable

With its extremely robust technology that meets the strictest industrial requirements, SINAMICS PCS is ideal for use in industrial and public grids. Thanks to liquid cooling, its operation is extremely efficient and all sensitive components are protected against thermal overload. SINAMICS PCS is remarkable for its consistently high quality and availability – basic prerequisites for reliable grid operation, particularly in harsh environments.

Icon energy efficency

Extremely energy-efficient

An important criterion for evaluating converters is their energy efficiency, which is exactly where SINAMICS PCS excels as a technologically optimized, high-quality series device. Effective liquid cooling not only ensures optimal cooling of passive components, but also a particularly energy-efficient operation thanks to a lower auxiliary power requirement.

Icon easy

Easy to handle

Choosing SINAMICS PCS means choosing a simple way to reach your goals. It starts with simplified selection and configuration, plus time-saving engineering based on a validated simulation model. With SINAMICS PCS, you also benefit from an especially straightforward ordering system with only one order number and simple commissioning. SINAMICS PCS comes “ready to connect,” having been designed and tested in advance as a standardized version.

Icon certified

Certified according to VDE-AR-N 4110

As a certified power generation unit according to VDE-AR-N 4110, SINAMICS PCS can be used to connect battery storage systems to the public medium-voltage grid. It thus simplifies plant certification and saves you time and money when procuring the plant certificate. As the unit certificate is available, project planning and execution are also accelerated and in addition, the validated simulation model of the SINAMICS PCS power generation unit is included in the scope of delivery.

Icon digital

Simply digital

Imagine your power conversion system supplying you with important information about its condition. SINAMICS PCS can visualize and monitor through PROFINET important operating states based on more than 1,000 converter parameters. SINAMICS PCS can also be optimally integrated in the overall plant simulation ahead of time, thanks to its simulation model. This enables you to draw conclusions about interactions between the plant and components in advance. And thanks to SINAMICS Startdrive in the TIA Portal, the converter can be integrated especially quick and easy in drive technology. 

Icon global

Global support

With SINAMICS PCS, you can count on optimal support from our experts worldwide. They stand ready to assist you around the clock, either on site or via remote access. The uniform look and feel of customer documentation also makes it easier for you to find what you need, especially since we offer you a complete solution with our one-stop shop concept. And when it comes to spare parts provisioning and maintenance, you naturally benefit from the large number of identical parts in the SINAMICS family.

SINAMICS PCS

Predestined for industrial and public grids

The specific functions of SINAMICS PCS make it ideal for use in industrial and public grids, as well as in microgrids.

Your benefits: lower costs, less CO₂ emissions

For an operator of industrial grids, one of the most important aspects of power supply is cost. How can you minimize procurement costs and improve the reliability of your plants? You immediately enjoy multiple benefits when you connect a battery storage system with SINAMICS PCS to the renewable in-plant power generation.

Visualization optimization of electricity costs

Optimization of electricity costs, thanks to peak shaving

Cover peak loads with power stored from when usage is lower. This lets you take optimal advantage of the contractually agreed electricity demand and avoid additional costs for peak demand periods. You also improve your supply reliability, because you’re able to cover peak loads independently of the grid.

Visualization backup power

Backup power: reliability for your plants

In the event of a power outage, an appropriately dimensioned battery storage system provides you with sufficient power to stabilize ongoing processes and coordinate their termination. This helps you to avoid potential damage to your plants and the resulting production outages.

Visualization green footprint

Green footprint: optimally deploy your resources

If you have your own power generation, battery storage is the optimal way to compensate for volatility, for example in the case of PV or wind energy. This allows you to cover your own requirements with as much carbon-free electricity as possible.

 

Visualization STATCOM

STATCOM: compensate reactive power

SINAMICS PCS can be used to compensate reactive power in the industrial grid, and in this way comply with the power factor in accordance with the grid operator’s specifications. This enables you as operator to optimize your energy costs.

250 V – 500 V AC
DC voltage range
460 – 1,100 V DC
Output
435 – 870 kW

Your benefits: improved performance, greater supply reliability

For applications in the energy sector, the combination of SINAMICS PCS and battery storage systems also provides optimal opportunities for improving performance and supply reliability. In some cases, suitable storage can enable you to avoid investing in the expansion of existing power generation capacities.

Visualization battery storage

Battery storage for peak shaving

Optimize your power distribution, thanks to battery storage systems and SINAMICS PCS. The long-term coverage of peak loads through energy storage allows you, for example, to avoid costly expansions of your power distribution system.

Visualization frequency regulation

Frequency regulation

Fluctuations between supply and demand in the power grid result in instabilities in grid frequency. A combination of battery storage and SINAMICS PCS can compensate for these frequency fluctuations, supplying instant power to the grid when the frequency is low and absorbing excess energy from the grid when the frequency is too high.

Visualization blackstart

Blackstart

You also benefit from the combination of battery storage and SINAMICS PCS when you have to restart a power plant. Simply draw on stored energy instead of a diesel generator.

Visualization Microgrid

Greater stability in Microgrids

Use a battery storage system in conjunction with SINAMICS PCS specifically for stabilizing a microgrid consisting of just a few power generators. This guarantees a high-quality power supply and high supply reliability even without a grid connection.
