Description

technical field [0001] The invention belongs to the field of simulation devices for teaching or training, and in particular relates to a training method for relay protection operation and maintenance of 10kV switch cabinets. Background technique [0002] In recent years, the business form of power grid operation and maintenance and the composition of power grid operation and maintenance personnel are undergoing tremendous changes. In terms of operation and maintenance business, with the rapid expansion of power grid scale, rapid update of operation and maintenance technology, and more types of operation and maintenance business, the business volume of traditional business and new business of the operation and inspection department has increased at the same time, especially in the secondary operation and maintenance department , There are many new types of business, which has brought about a doubling of the business volume. In terms of personnel composition, the proportion o...

Problems solved by technology

[0016] 2) Virtual reality technology training requires special hardware equipment, the training is still not convenient enough, and the learning cost of the equipment itself is relatively high, requiring additional practice and familiarization

On the other hand, the number of concurrent users will be limited by the number of hardware devices

[0017] 3) Although some 3D circuit simulation tools have appeared at present, the algorithm is too complicated and not suitable for the simulation of the secondary circuit of the switchgear

The secondary circuit of the switchgear is composed of several complex AC and DC circuits, among which there are dozens of components that can be controlled by humans or machines. Basically, all components have only two states of on and off. The overly complex simulation algorithm is inefficient. The real-time calculation requirements of the secondary circuit of the switchgear cannot be realized
