RTU with IEC 101&104 ProtocolRTU (Remote Terminal Unit) for providing real time power data to Load Dispatch Center. It provides Analog Parameters including MW, MVAR, Voltage and Frequency and Status points of Circuit breaker, Isolator, Sequence of Events(SOE) to Control Station.
What is RTU?RTU is an electronic device that interfaces objects in the physical world to SCADAsystem by transmitting telemetry data to a master system. RTU acquires various analog and digital parameters using appropriate devices for data acquisition and sends data to SCADA master in the required format or protocol.
Why RTU?As per CERC regulation, IPPs, CPPs, Open Access Customers are required to provide real time power data to the respective State Load Dispatch Center (SLDC). The real time power data can be obtained and provided to SLDC using a RTU (Remote Terminal Unit). The generating companies are required to provide the data by installing a RTU at their plant to the respective State commissions using appropriate communication media.
What is Open Access?Open access in transmission is an initiative by CERC to promote competition amongst the generating companies (IPP/CPP) who can now sell to different distribution licensees across the country. This led to availability of cheaper power. The Act mandates non-discriminatory open access in transmission. Due to open access to distribution networks introduction by the respective State Commissions for enabling bulk consumers to buy directly from competing generators,
competition in the market has increased the availability of cheaper and reliable power supply. The Regulatory Commissions need to provide facilitative framework for non-discriminatory open access. This requires load dispatch facilities with state-of-the art communication and data acquisition capability on a real time basis. It is mandatory for the power generating companies to provide real time power generation data to state Commissions by installing RTU (Remote Terminal Units) at their plant.
