[Abstract]:The accuracy of relay protection setting is of great significance to maintain the safe and stable operation of power network. The on-line setting of protection setting is the inevitable requirement of the development of smart grid. Based on the energy management system (EMSS) which is widely used in power grid dispatching, an engineering design method of on-line setting calculation system for smart grid relay protection is presented in this paper. Based on the engineering practice of Chengdu Power Grid, the feasibility and extensibility of the proposed engineering design method for on-line setting calculation system of smart grid relay protection are verified. The main work and innovation of this paper are as follows: (1) based on the object-oriented technology and C / S structure, the engineering design method of the intelligent power grid relay protection on-line setting calculation system based on the energy management system is studied. The premise and foundation of on-line setting of protection and value is to obtain real-time, accurate topology diagram EMS is widely used in all levels of power network dispatching in China, which can provide a good data platform for setting the value of relay protection. It is helpful to ensure the correctness of the fixed value. The engineering design method studied in this paper obtains the data directly from EMS, which avoids the tedious input work of the basic data of the power network. The development method of data interface between setting computing system based on object-oriented technology and EMS is discussed, and the interface between setting computing system and EMS system is realized. In order to obtain the power network model and real-time operation data in EMS system, the interface between the setting calculation system and the fault information system can be realized at the same time, and the communication between the value setting system and the fault information system can be completed. On-line tuning. 3) A multi-set automatic switching method is proposed to adjust the operation mode. In order to make automatic switching more practical and easy to maintain, based on the C / S structure, all possible topologies are lifted in the local client to represent open loop points, scheduled overhaul, system failures, etc. The generative representation of the different content in each case, and transferred to the server, in case the same running mode can be quickly called, and graphically generated configuration diagram for the user to use.
