Information Security Strategy Of Trade In Electricity Market Based On Time-Space Characteristics Model

With the development of China's power corporation, there are great advance of our power market, the relationship between electricity trade system and national economy and our life are more closer than before, the electricity trade's problem have directly influence on our economy and our life. To make a reliable power system depends largely on the security of data and information network of power corporation. Any secure problem of the data and information network will directly influence the power supply and people's living, so the research on the information security of trade system in power market is of meaningful.At first, studying information flows from macro to micro aspects in power system & trade market, power market trade systems & information interfaces, as well as interior electricity trade. Then, pointing out the hidden troubles in all sections of information flows. After that, thesis analyzed the different information characteristics in time field and space field. For the availability, integrity, confidentiality and non-repudiation in the process of electricity trade, the information security model of electricity trade based on information time-space characteristics is proposed.Combined with this model analyzed the security requests of multi-levels and succession in electricity trade. Based on it and combined with the division of safety districts in secondary systems security protection, discussed in detail the information security protection strategies of power trade in electricity market circumstance.In the final part of this thesis, by the help of information time-space security model and security strategies in electricity trade, combined with author's engineering experience in this field, discussed the engineering application of information security strategies in Ertan Hydropower Development Company Ltd.Information security issues discussed in this thesis as well as tightly concerning to real engineering applications, are also available in every aspect of data network. The solution can be used in many similar systems.
