In cooperation with ATC Automation Systems, the installation of the necessary SCADA equipment for the interconnection of 80 photovoltaic projects in a 20/150kV substation in the area of Domokos started.

Equipment and equipment20/150kV substation equipment

The Rack was moved and connected to the 20/150kV substation, where the servers, the ups, the firewalls, the protocol converter and the central SCADA program, which will cooperate with the RTU of ADMIE, receiving the data (e.g. set point) and sending the necessary information. WiFi system

The installation of wifi antennas was also started, in order to ensure the best possible transfer of data and commands to the server, independent of the other systems (cameras, alarms, etc.).

Equipment FB projects

The racks of the PV projects were transported and started to be installed, including gateway equipment, plc, switches, power meter etc., which will collect the data from the park (inverters, MT etc.) and transfer them to the central server.

MainTech, in cooperation with ATC Automation Systems, undertook the supply and installation of a SCADA system in 100 PV Stations and the central substation 20/150kV, to which the parks are connected, through a Common Exclusive Network of PV stations in the region of Central Greece. 

What is the SCADA System

According to the requirements of the connection contract of ADMIE for PV PV projects connected via the Common Exclusive Medium Voltage Grid to a High Voltage substation, an appropriate system must be installed which will be able to manage the data of the PV parks and the TS. Its ultimate purpose is to inform the UNMEA’s CEC, receive orders and implement the scenarios given to it. 

SCADA Integrity Platform

The heart of the proposed system is the new platform SCADA Integrity of the company ATC Automation Systems. The Integrity platform is the new generation platform which has inherited several technologies from the older ATCAS Supervisor platform used in several wind farm projects and CHP plants. The new platform has been developed in .NET6 environment and supports sending and receiving data to and from Cloud platforms.

Monitoring of PV via the Cloud platform

Understanding the monitoring requirements of a PV park (generation, outages, faults, FOSE, set point from ADMIE, injection limitation etc.), as well as the volume of projects, but also the interaction between them when connected to common networks, we develop the application  PASS IoT Portal, which enables monitoring, evaluation and maximization of park output by connecting in one system, data from inverters, low voltage, average voltage,  meteorological data, as well as interaction with alarm systems, cameras.
