Direct digital control is the automated control of a condition or process by a digital device (computer). Direct digital control takes a centralized network-oriented approach. All instrumentation is gathered by various analog and digital converters which use the network to transport these signals to the central controller. The centralized computer then follows all of its production rules (which may incorporate sense points anywhere in the structure) and causes actions to be sent via the same network to valves, actuators, and other heating, ventilating, and air conditioning components that can be adjusted.

This invention discloses a multifunctional integrated power metering training device and its simulation method, belonging to the technical field of power system training equipment. It includes a main control cabinet and an operation panel area. The main control cabinet adopts a double-layer steel frame structure, housing an 8300D power source, current transformer, voltage transformer, and industrial control computer. The 8300D power source, based on virtual load digital power supply technology, achieves high-precision power output through computer software programmable control to simulate the metering environment of a real power field. The operation panel area includes a meter installation and connection panel area and a simulation test panel area. The meter installation and connection panel area is equipped with a power meter and a perforated plate; the perforated plate supports installation and wiring training. The simulation test panel area is equipped with a miswiring operation area and an anti-theft metering operation area. This solution organically integrates modular design, intelligent innovation, and direct digital control technology into the power metering training device, achieving high reliability, scalability, and intelligent fault handling capabilities.
