Construction of a modern SHP equipped with an innovative control system and PMG generators
Historical overview
The first small hydropower plant at the cascade inlet to Lake Dzierżno Duże was built in the early 2000s. The facility was built using the economic method and was equipped with four propeller turbines. These units were installed near the fourth cascade, on an I-beam steel structure connected to the tin building structure of the SHP. Water was supplied to the facility by a steel pipeline. The power station as described continued to operate for years to come. Unfortunately, the technology of construction began to take its toll on the operation of the facility over time – greater failure rates of the hydrosets and increasingly cumbersome maintenance. The new owner of the power plant has finally made the decision to build a modern facility in place of the old small hydropower plant. IOZE Hydro completed the investment, fully utilizing the hydroelectric potential of the location.
Parameters
Technologies used
- Two vertical Kaplan turbines
- Two generators of 200 kVA each
The facility was equipped with a control and automation system dedicated to small hydropower. For the Łabędy SHP, we designed and manufactured a unique turbine regulator system. The hydroelectric power plant is equipped with PMG generators, not supported by an inverter. Generators of this type have a very high efficiency (up to 97%), significantly higher than asynchronous generators. s. In the case of a system equipped with a generator with permanent magnet excitation, there is no need to compensate for reactive power, which translates into major savings for the start-up equipment and operation of the facility.
Investment planning:
- Acquisition audit of the facility
- Evaluation of available hydropower potential
- Optimising the choice of hydroset technology
- Financial and technical advisory
Consulting and Design:
- Advisory to maximise the gain on sale of generated energy
- Developing a complete set of design documentation
- Acquiring a construction permit
- Support in acquiring external financing
- Obtaining a guaranteed energy sales price for a period of 15 years
Execution of construction works as a general contractor:
- Erection of the power plant building with ancillary infrastructure
- Manufacturing and delivery of the complete Kaplan turbine technology
- Expansion and reconstruction of the reinforced concrete water intake
- Reconstruction of the water supply pipeline to the turbine chamber together with the installation of fittings in the throttle chamber
- Renovation of the existing weir by replacing the closure system (including its lifting mechanisms) and its automation
