When the relay protection devices are interfered in the power system, if there is a fault, it will affect the overall security of the power grid, resulting in the power grid cannot operate stably. When the interference energy exceeds the maximum allowable energy of the logic circuit, it will directly damage the components and affect the normal operation of the relay protection device. Therefore, strengthening the anti-interference ability of relay protection and automation devices has become an important topic in power system.展开更多

Several aspects such as embedded design technique adopted in the system framework, application of adaptive theory in data acquisition, Board Support Packet (BSP) developing and task dispatching related to operating system are discussed. Both hardware and software framework of the system are given. Advanced hardware platform and software development environment is applied in design of the system, with the advanced co-design technology.展开更多
