SCADA solutions for the monitoring of photovoltaic plants Solar photovoltaic energy is currently one of the cheapest sources of renewable energies. The continuous rise of the price of electrical energy and the optimisation of the prices of every part of a photovoltaic power station are directly leading to increased investment in these systems. For this reason, the average installed power in new plants is increasing on a daily basis, making it necessary to have systems that are capable of continuously monitoring and managing the facilities and interacting with all of their elements, thus...

SCADA solutions for the monitoring of photovoltaic plants Customised monitoring Every solar energy plant is different, no two are the same. Nowadays, you can find some installations with fixed photovoltaic panels, others with solar trackers or a combination of both. This means that each facility is unique and the points being measured are also different. For practical purposes, a photovoltaic plant is divided into three monitoring areas: The Photovoltaic area, Power area and the Control area. CIRCUTOR has a wide range of products, which allows us to supply a solution for each of the above...

SCADA solutions for the monitoring of photovoltaic plants Photovoltaic area The photovoltaic area is the first measurement level, where the measuring equipment of each string of panels (PV) is found. There are also various sensors, to determine the operating conditions of the panels; these include solar radiation meters, wind meters, solar trackers, etc. Stringbox String measurement and protection panel. The main element that is installed in a photovoltaic area is commonly known as a Stringbox. CIRCUTOR's Stringboxes are panels with a compact design, for installation in environments with...

SCADA solutions for the monitoring of photovoltaic plants The number of measuring devices varies, depending on your method for monitoring the plant. You must consider this operating method before selecting the exact quantity to be installed. Control devices In addition to Stringboxes, the photovoltaic area has devices that collect information regarding the weather conditions, and sometimes what are commonly known as solar trackers, to move the photovoltaic panels according to daily variations in solar radiation. The following elements are part of the control devices: Solar tracker A 1- or...

SCADA solutions for the monitoring of photovoltaic plants Project design Power area The power area is the second measurement level of a photovoltaic power station. At this level there are various Power Centres, which are interconnected by a fibre optic ring. The power centres are enclosures that are spread across the entire power station and which connect the different stringboxes to the input of an inverter to convert their current from DC to AC. Inside the power centre there is also a medium voltage impedance elevator transformer, which collects all of the energy from the inverter and...

SCADA solutions for the monitoring of photovoltaic plants Monitoring the efficiency of the INVERTER By monitoring the inverter's input and output, you can see how it is performing. It allows you to know the volume of losses and enables the early detection of any anomalous behaviour by the inverter. AC MEASUREMENT, THE INVERTER'S OUTPUT OP.1 CIRWATT-B Meter for taking energy readings at the inverter's AC output. OP.2 CVM-B100 Analyser system that records energy at the inverter's AC output. Both the CIRWATT-B and CVM-B100 options have the same function, they record the energy at the...
