Scope:

Design, supply, installation, and commissioning of SMU (String Monitoring Unit), SCADA and weather monitoring station with a sensor for Solar Power Plant monitoring and control of 500 kW grid tie solar Power plant at KSEB.

Background:

KSEB is under the process of erecting a 500 KW Solar power plant at one of their 110 KV substations. KELTRON got the turnkey project.

The customer is looking for a solution for Supply and installation of String monitoring unit, SCADA & Weather monitoring station with a sensor for Solar Power Plant for monitoring and control of 500 kW grid tie solar Power plant.

A SCADA is provided in which the operator can view real-time and historical data. Besides that, there is an option to monitor and control the data remotely over the internet.

Weather monitoring station, SMUs and inverters will be communicating with SCADA over Modbus RTU protocol. Weather monitoring station includes Pyranometers, Wind speed sensors, ambient temperature sensors and module temperature sensors. The environmental sensors will be providing the values as analog 4-20 mA. There is a converter which will integrate all the analog signals to RS485 and communicate with PLC and SCADA.

The breaker is hardwired to the PLC. It helps regulate status from the breaker and the control of the Breaker without any time lag.

All the parameters are stored according to the guidelines and the data can be generated as reports in trends and cumulative graphs. This system is integrated into the network and will provide all the features to three number of web-based clients.
