Kaniv Hydroelectric Power Plant

Kaniv HPP is a major station of the Dnipro cascade, running 24 horizontal bulb-type hydro units under a long-term modernisation programme. The assignment focused on relay-protection commissioning for a hydro-generator in the approximately 24 MW class, together with a separate protection scope for a generator block comprising five units — delivered as a single, coherent multi-vendor protection package.

• Commissioned and tuned generator protection on ABB REG650 and Siemens SIPROTEC 5 platforms, applying the approved protection philosophy to the hydro-generator and its associated generator block.
• Verified measurement circuits and protection inputs for current, voltage and frequency quantities, together with the corresponding binary status and command signals.
• Configured and checked the applicable generator protection functions — differential and earth-fault protection, voltage and frequency supervision, power-related protection, thermal monitoring and backup overcurrent — in accordance with the project scheme.
• Checked protection logic, trip matrices, blocking/permissive conditions and the interfaces to generator circuit-breaker control and plant automation.
• Performed functional testing of protection pickup, alarm and trip paths and validated event/indication behaviour for commissioning and subsequent maintenance diagnostics.
• Coordinated settings and logic between ABB and Siemens devices so that the protection package operated as one consistent multi-vendor system.

This assignment strengthened the protection layer around generating equipment by combining device-level configuration with end-to-end verification of the complete protection path. Particular attention was paid to correct coordination between independent protection channels and the plant control system.
