Hydropower engineering

We have been operating in the field of hydropower for over forty years. We supply control systems and know-how for small and large hydropower plants and hydraulic structures, including auxiliary operations. We carry out deliveries for the management of individual technologies and entire units at the level of EPC projects, while we work with our own SandRA control system.

Based on a long history of supplies to hydropower plants, we have a wide portfolio of products that we are able to apply in this sector. We provide comprehensive supplies from the design of a new solution or modernization through the implementation of the project to commissioning. Field instrumentation and cabling are also standard.

Control and management systems

Project solutions for operated and newly built hydropower plants of all types

Own development

SandRA's own platforms, enabling adaptation to different types of technologies in operation

Tradition and stability

Control systems for hydropower plants
to more than 20 countries 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

Accumulation and flow hydroelectric 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 hydropower 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

Product portfolio for hydro power engineering

DCS (Distributed Control System) - To ensure high reliability and security of controlled large-scale technological operations, we design and supply a distributed control system on our own SandRA Synergy platform. DCS also includes HMI (visualization) at the level of engineering and operator stations. Functions such as data archiving, simulation, etc. are a matter of course.

Our company has long-term experience in setting up power blocks at thermal power plants of various outputs. The ZAT control system is ready for data processing and control of individual operating files, including comfortable control and visualization. We use the SandRA Synergy product on the Z200 platform for the control and diagnostics of power blocks.

We provide monitoring and visualization with the help of products from Czech and foreign manufacturers. Products from Czech manufacturers include software applications from Geovap (Reliance) and Moravské přístroje a.s. (ControlWeb). From abroad, the applications are Aveva (InTouch) and Siemens (WinCC). If necessary, we can implement a project with SW Cimplicity. We provide a complete supply, including field instrumentation and cabling.
