The IREM solution for off-grid hydroelectric plants can also be developed with different levels of automation to better meet the specific requirements of the installation site.
Starting from the simplest and most widespread systems, equipped with manually controlled hydroelectric turbines, it is possible to implement fully automated and remotely controlled plants.
In these cases, the IREM control and automation panel interfaces with the plant using and distributing the generated energy, in order to optimise the management of the various components involved.
To regulate electrical parameters, the IREM system uses the constant load operating principle.
This system, in addition to having very short response times (1/150 of a second), guarantees a high level of Power Quality for the served users.
The needs of stand-alone systems vary significantly depending on the type of load and the geographical area in which they are installed.
Sites characterised by a considerable variation in available flow rate and by complex management of the generated electrical power—such as mixed systems with cogeneration of electrical and thermal energy—are well suited to highly automated systems, even when off-grid.
The complexity of these plants requires a fully automated turbine-generator group, paired with an automation panel capable of managing the produced electrical energy and the different connected loads.
These hydroelectric power stations often replace existing diesel-based systems, contributing to a significant reduction in CO₂ emissions.
