DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0023] Current power plant operations and management generally rely on manual on-site control, lacking efficient automation and remote control. This results in slow system response, low O&M efficiency, and an increased risk of human error. With the continuous expansion of power systems and the advancement of smart grid construction, traditional, largely manual power plant operating systems are no longer able to meet the real-time, security, and flexibility requirements of modern power dispatch. Therefore, building a smart power plant operating system that supports remote monitoring and automated execution has become a key technical direction for improving power plant management efficiency and ensuring safe and stable operation.

[0024] Based on this, embodiments of the present invention provide a power plant remote control device and system. This technology uses a remote control device to control the power supply of the load, improving power plant management efficiency, safe and stable operation, and ensuring smooth load operation. To facilitate understanding, a power plant remote control device is first introduced.
