Introduction
A power generation company Renew power private limited specializes in erecting and commissioning of hybrid power generation (renewable energy) projects such as solar farms, wind turbines and hydroelectric power. The company has multiple remote sites, each equipped with data acquisition devices and SCADA for monitoring and controlling the grids. The management realizes the importance of human safety while operating the USS 33Kv circuit breaker, to address the need for human safety GEISPL proposed an intermediator DAQ system between USS ( Unitized Substation ) & PSS ( Pooling Substation ) to ensure the human safety at site.
Overview
In USS, When 33Kv CB trips due to any of the technical conditions like internal short circuit in transmission tower , internal issue inside the turbine/ transformer etc.. At PSS, the turbine will shut down. The SCADA will receive the information regarding the turbine working status however at this stage SCADA will not able to derive the reason behind the turbine shutdown.
Conclusion
By implementing, the Intermediator DAQ System between USS and PSS at Renew power private limited successfully addresses the challenges of to related human safety, feasibility of remote access between the sites and reporting at RE site by removing the access to local USS users. Now all control will be given to the authorized PSS users through remote access. The company can employ only the authorized personnel to monitor and control the USS 33Kv CB. The solution contributes to the company’s overall safety of manpower and time management working at WTG HT yards.
