| Abstract: | It is rare to see a fission reactor in series connected to the low voltage side of the transformer in a step-down substation. In such a special system, there are a few bugs in the existing design of its relay protection, which lead to practical problems. In this paper the design bugs are analyzed in detail using the basic principles of relay protection. A number of solutions are proposed to these problems. The advantages and disadvantages of the solutions are investigated and compared, and tentative conclusions are provided. |
