Great emphasis is put on reliability and high energy efﬁciency of the equipment used for the production and distribution of energy. In order to monitor and prove these properties, we need a powerful management system which reliably collects data from manufacturing plants and stores them in an independent database protected against unauthorized intervention. Data must be presented in a form which provides a clear overview of measured and derived parameters and allows for the sufﬁcient ﬂexibility necessary to create one‘s own assemblies and overviews, and ﬁnally, which enables the user to compare, examine and evaluate data.
In order to evaluate the efﬁciency of photovoltaic power plants, ContPort calculates so-called derived parameters, such as the amount of consumed electrical power or system power indicators compliant with EN 61724. For different types of manufacturing plants/ power plants, the system mostly displays accumulated values from meters and statuses of switching elements, and overcurrent and overvoltage protection devices. These values are available on a dashboard or in customer reports generated at predeﬁned intervals. Breakdowns, such as downtimes of strings or inverters, or lower production than expected by the system based on current conditions, are immediately reported via e-mail or SMS.
Thanks to the integration of meters and current values, investors and technology managers always have a comprehensive overview of the status of the monitored technology. ContPort can also import data from other control systems and SCADA, and therefore enables comparison (benchmarking) of the technologies available in the entire manager portfolio.
