Because many older power stations face efficiency and wear-and-tear issues similar to those at this plant, Nidec Industrial Solutions sought to develop a solution that that could be scaled up or down for a variety of similar applications.
The modular solution Nidec developed replaces the original system with an MV system capable of starting and regulating a power station’s motors. The solution allows the owner to synchronize the two pumps at the power station – whether they are fed directly on line or in variable speed configuration by the inverter – in a variety of configurations. The result: smooth, “bump-less” transitions. The system’s flexibility increases power production efficiency, while also reducing equipment stress.
The inverter installation was completed during a brief shutdown that had been previously scheduled for plant maintenance. Due to the project’s short window for completion, Nidec performed a simulation of the entire system in its test facilities prior to installation. That involved coordinating integration activities with the power station’s operations staff, MV switchboard supplier and DCS supplier. The simulation helped to ensure that the MV system would integrate seamlessly when it was installed at the power station.
Final commissioning was completed on schedule. The scalable design of this modular power solution makes it possible to be adapted quickly for similar projects.
