Problems solved by technology

However, since the protection device running on live is not allowed to operate at will, the lack of practical tools has become a difficulty for the team to carry out the training of protection device operation skills
[0003] Traditional protective device operation skills training is mainly carried out in conjunction with the planned work of protective device operation. During the implementation process, there are the following problems: 1. Since the training work is carried out on the job site, it is necessary to specially organize trainees to go to the site to learn, and the organization cost is high. Contradictions are prominent; 2. The on-site working time is tight, and at the same time, the operators need to maintain focus to ensure the quality of the work, so they cannot also serve as trainers to explain; 3. There are many people on site and small equipment, so it is difficult to see the operation steps and content of the operators. ;4. When carrying out training in conjunction with the planned work, the trainees can only watch, not practice, cannot consolidate the learning effect, and cannot check the trainee's learning effect; 5. Since most substation 110kV line protection is equipped with only one type of protection device, so each on-site training basically can only learn one type of equipment, so the training efficiency is low
[0004] Based on the above information, it can be seen that the traditional protection device operation skills training, which adopts the method of training in conjunction with the planned work, has low efficiency and unsatisfactory results, and cannot meet the needs of safe and stable operation of the power grid.

Embodiment 1

[0036] see figure 1 The above-mentioned high-simulation protection device simulation operation training system provides three modules: free operation mode, training mode and examination mode.

[0037] Among them, the free operation mode is the basic functional module, and its essence is to use simulation technology to simulate the protection device that operates on-site and does not allow random operation into a virtual device that can run on a tablet computer. Users can perform common operations such as setting value modification, soft platen switch and withdrawal, and modification of control words on the virtual device without any constraints. Therefore, through the free operation mode, you can be familiar with the operation method of the protection device, the device menu structure, parameter information, etc., and it can also be used as a rehearsal tool before the daily work of the team to improve work efficiency and reduce operation risks.

[0038] The training mode is b...

Embodiment 2

[0041] see figure 2 , the above-mentioned method based on physical picture simulation is used to construct a virtual device consistent with the scene, which includes the following steps.

[0042] Step S01, collect the panel picture of the on-site protection device; first process the picture into a format that can be used for programming; then use the picture processing software to perform necessary beautification; finally set the picture as the scene background of the software page as the virtual protection device panel;

[0043] Step S02, collecting liquid crystal display information of all levels of menus and function module parameters of the on-site protection device, and then using a programming language to write a class that simulates the above liquid crystal display content. This class should have the display, modification, and refresh functions of the above liquid crystal display content to simulate liquid crystal display The display content is displayed on the liquid cr...

Embodiment 3

[0047] see image 3 , the training mode is realized on the basis of the free operation mode, and its core is a training process control method, which includes the following steps.

[0048] Step S11, the training mode provides students with common operation learning tasks of different types of protection devices. After students select a learning task, they immediately enter the operation interface of the corresponding type of protection device, and at the same time generate an array of key operation sequences for the current task. The array content includes key operation sequence, The coordinates of the operation prompt and the content information of the operation instruction dialog box;

[0049] Step S12, after entering the learning interface, the student can see the operation prompt and the prompt dialog box. The correct operation for the student is to click the button under the operation prompt. After clicking, the system will immediately compare the operation button with t...

Abstract

The invention discloses a simulation operation training system of a high-simulation substation protection apparatus. A set of virtual protection apparatus capable of being subjected to touch screen operation on a tablet computer is designed by adopting a real object picture simulation-based method; a panel, an operation method, an operation process and a liquid crystal display effect of the virtual protection apparatus are kept consistent with those of a real device; and the simulation operation training system comprises three modules including a free operation mode, a training mode and an examination mode. The simulation operation training system has the beneficial effects that the operation experience consistent with that of the real device is constructed; a self-study guide function is creatively added; a user can perform operation and self-study at the same time according to operation prompts and is familiar with device operation in a game, so that teachers are reduced; in the examination mode, whether the operation of a student is right or not is automatically judged, and the operation of the student is objectively scored; the touch screen operation of the tablet computer is supported; a human-computer interface is friendly; and the system is intuitive in operation and convenient to carry, can repeatedly perform practical operation intensive training, is strong in pertinence, is used during learning, and also can serve as a risk rehearsal tool of a pre-shift meeting of a team.

Description

technical field [0001] The invention belongs to the technical field of electric power training simulation, and in particular relates to a training system and method for simulated operation of a high simulation protection device. Background technique [0002] When the operation mode of the power grid changes, it is necessary to perform operations such as setting value cut-off area, setting value modification, soft pressure plate switching, etc. for the protection device. Protection device operation skills are the guarantee for the safe and stable operation of the power grid, and are also the core skills for substation operation and protection personnel; when the operation mode of the power grid changes, it is necessary to adjust the parameters of the protection device through operation to ensure that the protection device can correctly reflect when the power grid is abnormal; relay protection Professionals say that there are "three mistakes", one of which is the wrong setting...
