Hydropower engineering
We have been active in the hydropower sector for over forty years. We supply control systems and expertise for small and large hydroelectric power plants as well as waterworks, including auxiliary operations. We carry out deliveries for controlling individual technologies or entire units at the EPC project level, working with our proprietary SandRA control system.
Thanks to our long history of supplying hydropower plants, we possess a broad portfolio of products applicable in this field. We provide comprehensive deliveries ranging from the design of new solutions or modernization, through project implementation, to commissioning. Field instrumentation and cabling are also standard components of our offerings.

Control systems for hydroelectric power plants supplied to more than 20 countries worldwide since 1970
Small hydropower plants
The system for the control and protection of small turbines is completely integrated in one compact cabinet. The switchboard contains a turbine control and protection system, which is implemented in the SandRA Z211CTC instrumentation. The solution can be delivered on a mounting plate, which the customer installs in their own switchboard.
Advantages of our supplies
- Simple solution, low purchase costs
- Lower operating costs due to greater reliability
- Cheap post-warranty preventive and corrective service (eg using remote diagnostics)
- The modernization of the excitation can be done without the need for large investments
- Simple operation, remote control of the excitation set
- SW modifications using remote administration and the possibility of extension to other services
Pumped-storage and run-of-river power plants
Our own long-term development and production allows us to adapt to the customer's needs in the areas of turbine regulation and control, generator excitation and control of the entire power plant.
We design and implement AVR Power and AVR Compact excitation systems for any type of synchronous generator using the ZAT AVR Z110 compact controller. Our deliveries include comprehensive solutions from basic design through implementation at the customer to warranty and post-warranty service. We also provide phasing equipment and supply of LV and MV electrical.
For the turbine control system (TCS), we offer our own SandRA Z200 control system or a system compatible with the control of the entire block according to customer requirements.
Advantages of our supplies
- Less electronic components and interconnections
- Easier commissioning and service
- Easy configuration using tools running on a Windows PC
- Adaptation for a specific application using device software configuration
- Programmable inputs and outputs
- Ensuring accuracy and speed of regulation thanks to the SandRA Z200 system
- Optional visualization according to customer preferences
- Easy connection to DCS process stations via internal Pernet communication
Pumped-storage hydroelectric power plants
We use the SandRA Synergy product on the Z200 platform for the control and diagnostics of power blocks.
Advantages of our supplies
- Control of power blocks of different powers
- Processing of a wide range of data and control of individual operational files
- Comfortable control and visualization
- Complexity of services in the modernization of control and management systems
- Guaranteeing compliance with strict security conditions, including cyber security
