Relay protection technology plays an important role in the development of thermal power plants and plays a significant role in improving the reliability and working stability of power supply systems in thermal power plants. In this paper, the setting calculation of relay protection devices in thermal power plants is briefly analyzed, specifically from three aspects: the working principle of relay protection devices, the problems in the relay protection setting calculation method and the implementation method of the relay protection setting calculation system. The normal and stable operation of thermal power plants is ensured by further optimizing the protection devices. 展开更多

Polysurfacic tori or kideas are three-dimensional objects formed by rotating a regular polygon around a central axis. These toric shapes are referred to as “polysurfacic” because their characteristics, such as the number of sides or surfaces separated by edges, can vary in a non-trivial manner depending on the degree of twisting during the revolution. We use the term “Kideas” to specifically denote these polysurfacic tori, and we represent the number of sides (referred to as “facets”) of the original polygon followed by a point, while the number of facets from which the torus is twisted during its revolution is indicated. We then explore the use of concave regular polygons to generate Kideas. We finally give acceleration for the algorithm for calculating the set of prime numbers. 展开更多
