Description
Integrated automation of a digital substation is built on the three levels, two networks scheme. The process, bay and station levels are linked by the station bus and the process bus, and all substation information is presented in digital form. The system includes station monitoring, protection, online monitoring of primary equipment, optical and electronic current and voltage transformers, intelligent terminals and merging units. It supports remote equipment control, programmed switching, condition-based maintenance and adaptive modes.
The event recording resolution is not more than 2 ms at the station level and not more than 1 ms at the bay controller level. A changed analog value reaches the station level in not more than 2 s, a change of a status signal in not more than 1 s. From the command to the start of execution takes not more than 1 s, and switching between the main and backup SCADA servers takes not more than 10 s. Bay controllers are built on a single hardware and software platform, accept CTs of 1 or 5 A, measure voltage and current with an accuracy of 0.2%, have a clock error of less than 1 ms/h, and synchronise by IRIG-B, PPS or SNTP.
Communication gateways come in two types. Real-time gateways transmit data, models and graphics to dispatch centres for remote control and telemetry, and service gateways operate alongside them. The hardware base is Chinese, with a Zhaoxin KX-6640 processor, 32 GB of RAM, a 1 TB drive, and domestic operating systems and DBMS. The gateway has 12 Ethernet ports, 8 RS-485 and 4 RS-232, redundant 110/220 V power supply, and supports the main power system protocols.
For distribution networks, NSA3100HD_D30 DTU terminals are intended for RMUs and distribution points with 8 or 16 bays in 4U and 6U enclosures. The 8-bay version has 100 inputs, 22 outputs and battery management. FTU terminals for overhead feeders have a 32-bit industrial processor and an embedded real-time OS, and withstand continuous overload of 2In and 20In for 1 s. The distribution automation system performs SCADA functions, diagnoses and locates faults, isolates the faulted section with network self-healing, and regulates voltage and reactive power.
The secondary system of step-up substations of wind and solar plants combines plant monitoring, primary frequency regulation, active and reactive power regulation and automated operation tools. The software core runs on different platforms, has a high-performance real-time database, supports SVG and CIM/G, redundancy and load balancing.
