| Abstract: | A secure dispatch communication network is essential to regular production and management of power system. The dispatch communication network is divided into real-time,quasi-real-time and non-real-time systems according to security classes. The principle of air gap is described and a scheme of layered dispatch communication network protected with air gap is brought out,which takes the real-time systems as the core layer. Its implementation and the construction of secure network are discussed. |
