[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0027] In the embodiment of the present invention, a semi-physical simulation operation training system for a diesel power station is provided. Figure 2 and Figure 3, since diesel power stations in the prior art usually consist of three parts: diesel engines, generators, and unit control cabinets, the "two in use and one in standby" mode is usually adopted, that is, two diesel engines run in parallel and one is on standby. The main operations of the power station are divided into two categories: machine-side operation and control cabinet operation. The automated diesel units are mainly in two modes: cabinet manual and cabinet automatic. Power supply process: In the cabinet manual mode, the operator first completes the start-up of two single units in the cabinet and switches from idling to full speed. Observe the indicator instrument, and close the circuit breaker after the unit is powered stably to complete the power supply of the single unit. At this time, the GPC (unit paralleling device) or manual synchronization table can be used to complete the paralleling of the second unit with the first unit. After the paralleling is completed, the second unit automatically closes and enters synchronization, and supplies power to the load at the same time. Operate the GPC control panel of the two units to transfer loads and distribute power. In the cabinet automatic mode: the operator first pre-selects the lead sequence. After the unit is started, the control program automatically closes and supplies power according to the pre-selected sequence. When the program detects that the load is too large and meets the conditions for parallel operation, the second unit automatically completes the parallel power supply, load transfer and power distribution under the control of two GPCs. When the city power is restored, the unit exits the power supply. The same exit power supply mode is also divided into two types: cabinet manual and cabinet automatic. Its action steps are opposite to the power supply closing sequence. Therefore, the diesel power station as an emergency power supply plays a vital role in maintaining the high reliability of the power system. In order to solve the adverse effects on the pre-job training of diesel power station operators such as the large number of components on the control panel of the diesel power station, the complex system principles, the many operating steps, and the great safety hazards of the unit caused by misoperation.
