PSCADA is provided with layered and distributed system structure in distributed arrangement and centralized management

The functions of the center and stations can be realized by this software and the functions of PSCADA subsystem can be realized by the close integration of line, software and the platform. Through this, layered, distributed, remote and real-time monitoring and control on operating conditions of electrical equipment including main power supply units for transformer substations, overhead line system (contact rail), etc. can be completed, and various abnormal accidents and alarm events of power supply system can be dealt with. Meanwhile, power supply system schedule, automaticity of management and maintenance, and power supply quality will be greatly improved to ensure safe and reliable system operation.

Monitoring objects include incoming power line, load switch, feeder line, transformer switch, DC breaker, low-voltage circuit breaker, traction rectifier unit, electric drainage cabinet (including stray current monitoring device), distribution transformer, AC/DC screen, rail potential limiter, braking energy consumption device, and other equipment. Application fields include subways, light rails and electrified railways.
