Background
Undoubtedly substations are one of the most important parts of electrical energy industry with big number of costly equipment and operations providing smart automation opportunities instead of manual data processing. Fast and accurate reaction to the resulting automated system will guarantee a reliable electricity network as well as maturing analyzed data.
Solution Overview
The smart grid system is a fully automated monitoring and controlling system designed for generation, transmission and distribution substations to precisely track the situation of equipment and unexpected faults. This advanced platform digitizes various manual operations into one resilient structure. It works based on a mature SCADA platform and several subsidiary objects like Industrial Ethernet Switch to fully operate a substation.
Our RWZ-1000 Substation Automation System can perform various functions such as protection, monitoring, communication and control, etc. based on the computer and network technology. It is a dispersed, hierarchical and distributed object-oriented system, in which the IEDs and computers are substituted for lots of devices with single function such as relays, meters, indicators, automation devices and panels. Local Area Network (LAN) is also substituted for plentiful cables. The protection relays in the system are relatively independent to improve the operation reliability substation and reduce the maintenance work. RWZ-1000 system can meet the requirement for substation automation put forward in CIGRE, that is, telecontrol function(telesignal, telemeter, telecontrol, etc.), automatic control function(Voltage and Reactive Power Control, Load-shedding, Static Reactive Power Compensator Control, etc.), metering function, protection relay function, function for protection relay(fault record, fault location, fault line selection), interface function(with microprocessor anti-maloperation, power supply, meters, GPS, etc.), system function(communication with station and local SCADA, etc.).
