Toro 3 hydropower project is operated by Costa Rica’s state-owned utility Instituto Costarricense de Electricidad (ICE). The US$190 million project is located in the Alajuela province and was co-funded by ICE, Banco de Costa Rica and utility company Jasec. Toro 3 powers over 60,000 households and is a continuation of the project’s Phases 1 and 2.
KONČAR Group was responsible for design, manufacture, delivery, supervision, setting up and putting into operation two 29.7 MVA hydro generators, including excitation systems, unit vibration monitoring systems, generator power and neutral point equipment, metal clad busbars and auxiliary consumption transformers. The solution was selected to monitor and protect the complex operations of the hydro plant and preserve the investment by focusing on critical machine parts according to customer requirements. The solution protects the plant by activating shutdown of the plant if critical values are reached.
The solutions is a modular and custom specific protection against all harmful parameters (vibrations, temperatures, air gap, magnetic field, partial discharges, cavitation) resulting with increased productivity and protected production. The plant operators can identify most important machine faults and get key information for effective asset management through expert tools. The problems like large inventory of spare parts and unplanned production shutdowns can be eliminated and prevented.
