Rural PV Solar Parks MONITORING AND CONTROL

Solar energy has been growing strongly in recent years, due to rapid technological developments in Photovoltaic (PV) panels and batteries. PV arrangements for rural areas brought new challenges, particularly in what concerns to online monitoring and control of equipment and production in remote areas. Nowadays Rural PV Parks still have no such monitoring and control systems, which significantly increases the risk of power outages and limits the quality of the service offered.

It provides online and real-time information of power production and consumption, as well as it is able to help preventing security threats. This information allows for a better energy balance management and an optimization of maintenance actions, leading to a more effective prevention of power outages, thus significantly reducing investment and operational costs.

Rural PV Solar Parks

Eneida has developed an innovative and robust solution to remotely monitor and control both performance and condition of Rural PV Parks.

MONITORING AND CONTROL

Rural PV Solar Parks

By default the EWS GIP-rg is able to acquire, log and process data coming from PV panels or string groups as well as from PV inverters, thus allowing for a very detailed monitoring of the asset. The EWS GIP-rg is also a Wireless Sensor Network gateway that allows the integration with other monitoring and control modules in order to enrich the capabilities of the system as a whole. Finally, it also supports communications via GPRS and GSM, making it ideal for integration with remote systems and software.

The Eneida’s Rural PV Solar Parks solution:

It is based on the smart device EWS GIP-rg, with aquisition, processment and communication capabilities, that works as the core of a modular and integrated system.

Monitoring and Control Extensions

The EWS GIP-rg, being a wireless smart device able to communicate within a WSN over the ISM 433MHz, 868MHz or 915MHz band, has the flexibility to increase the number of monitored parameters (such as humidity, temperature, sunlight, etc), as well as its control functionalities, with very low implementation costs. This is done by adding extra sensors and actuators that easily integrate with the EWS GIP-rg.

This can be done using the EWS SPP-r smart device (described ahead) which is able to detect intrusions and potential theft attempts in critical facilities, and that easily integrates with the EWS GIP-rg. In this case, the EWS GIP-rg is also able to control security sirens to signalize potential theft attempts.

Integration with Third-party Software

The EWS GIP-rg communicates over GRPS using the HTTP/HTTPS protocol and is prepared to interact with REST APIs. This makes its integration with third-party softwares as easy as possible.

› Remote and real-time energy balance evaluation;› Assets Condition Monitoring in a Predictive Maintenance framework;› Increased equipment lifetime;› Prevention of power outages and better QoS;› Instantaneous theft or fraud detection;

› Lower costs on monitoring and control systems deployment and operation;› Higher efficiency on the parks maintenance;› Reduction of investment and operational costs;› Higher performance on energy production and delivery.

This is a small and robust smart conductivity sensor, easy to install, ideal for use in demanding, remote and harsh environments. It allows for the detection of power shutdown and short-circuit, thus detecting and communicating intrusions and potential robberies in critical facilities, such as Photovoltaic Power Stations. The collected information is handled internally and transmitted over sub-GHz.

A smart and compact device for theft and fraud detection.
