Description

Technical Field

[0001] The present invention belongs to the technical field of relay protection of electric power systems, and in particular relates to a remote intelligent control system based on a relay protection laboratory. Background Art

[0002] Relay protection is an important measure to detect faults or abnormal conditions in the power system, thereby issuing an alarm signal, or directly isolating and removing the faulty part. Its basic task is to automatically remove the faulty equipment from the system within the shortest possible time and smallest area when a fault or abnormal condition occurs in the power system, or to send a signal to the on-duty personnel to eliminate the root cause of the abnormal condition, so as to reduce or avoid damage to the equipment and the impact on power supply to adjacent areas.

[0003] In order to ensure the correct operation of the relay protection device and avoid the situation that the power supply is affected by the staff's misoperation, practical training is required for the relay protection workers to ensure the practical operation level of the on-duty staff. Practical training requires the use of a professional relay protection laboratory. Due to the wide variety of relay protection devices and the high price of some equipment, it is very expensive to build a professional relay protection laboratory. In addition, the rapid replacement of relay protection devices further increases the necessity of practical training. At the same time, it also further increases the construction and maintenance costs of relay protection laboratories. This determines that professional relay protection laboratories cannot exist on a large scale and cannot meet the needs of many trainees and front-line relay protection workers. Conversely, there is a situation where the utilization rate of the laboratory itself is not high, resulting in a waste of resources.

[0004] Therefore, in order to solve the above problems, it is necessary to develop a remote intelligent control system based on the relay protection laboratory. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide a remote intelligent control system based on a relay protection laboratory. Remote control is used to allow personnel who have a need for relay protection testing to remotely control the equipment in the relay protection laboratory, thereby creating practical training opportunities for trainees who need practical relay protection skills and improving their work level.

[0019] Among them, the main station control end respectively performs local control of the inspection robot and all the equipment in the laboratory. The local control here only refers to the direct control connection of the main station control end to the inspection robot and all the equipment in the laboratory without the remote control intervention of the user terminal; specifically, the main station control end is communicated and interactively connected with all the equipment in the laboratory, including the laboratory large screen, the laboratory tested protection screen, the laboratory monitoring host and the server, and controls the above-mentioned equipment; specifically, the inspection robot and the laboratory tested protection screen are set one by one, and the inspection robot is controlled by the main station control end to implement the test operation of the laboratory tested protection screen corresponding to the inspection robot, and the inspection route of the inspection robot is to move around the corresponding laboratory tested protection screen.

[0020] Among them, the user connects to the main station control end through the user terminal, sends control instructions to the main station control end through the user terminal to apply for operating laboratory equipment and control the inspection robot to inspect the laboratory and operate laboratory equipment, thereby realizing remote control of the inspection robot and equipment in the laboratory.

[0021] Among them, the main station control end includes a local control module, a status monitoring module, a remote control forwarding module, and a local control intervention operation module connected to all equipment in the laboratory, and also includes a registration module, an appointment acceptance module, and a video guidance operation module that are interactively connected to the user terminal; the user terminal includes a user registration module, a main station login module, a reservation module, a main station equipment control module, and an application video guidance operation module.

[0022] Among them, the user terminal also includes a human-computer interaction module and an interface for users to perform manual operations, and the user terminal also includes a display screen structure for displaying test information, etc. The human-computer interaction interface includes the user terminal name, the user terminal boot menu, and the user terminal boot menu version number, wherein the user terminal boot menu includes user accounts, laboratory lists, laboratory reservations, tool lists, test plans, equipment inspections, external devices, remote guidance, robot control, equipment locking, test reports and system settings; users choose to log in to the laboratory, reserve laboratory test time, call laboratory tools, compile test plans, control inspection robots to perform inspections, protect tests and other operations through the user terminal boot menu.

[0023] When the present invention is implemented, the user can log in to the main station through the user terminal to apply to operate the laboratory equipment. The main station control end receives the instructions sent by the user terminal and forwards the control instructions to the inspection robot. The inspection robot observes the image and feeds it back to the monitoring host and the large screen of the laboratory. The inspection robot can work around the inspection route of the corresponding laboratory protection screen under test. The inspection robot can operate the protection screen under test in the relay protection laboratory within the inspection route. The inspection robot and the protection screen under test in the relay protection laboratory will feed back the test process and results to the main station control end.
