Analysis And Implementation Of Enmics For A Petrochemical Project

Petrochemical projects management of qingyang substation has been by human management way to give priority to. Data on the record within each substation on duty of the staff written records, small amount of data record, basic recorded on the problems and several times a year of search data record as regular. This creates a substation equipment in often failed and when the power trip had been found that can repair, petrochemical factory production to bring great losses. According to the defects of the management qingyang petrochemical substation and loopholes, to reduce and avoid petrochemical factory in the power supply because production problems, the substation management system needs reform. The reform is the core of the data in the transformer substation of real-time records, the calculations of the transformer substation, and can in data of calculation and collection capacity as the basis of automatic monitoring and appropriate form of control, drawn out this paper topic, substation automation control system.In this paper the transformer substation of existing qingyang petrochemical characteristics, loopholes and from within the transformer substation equipment data of information collection, calculation and information of each circuit monitoring and control between the perspective of needs analysis, and in the analysis is conducted on the basis of the analysis of the hierarchical system. Through the analysis, the qingyang petrochemical substation automation monitoring system should be divided into the terminal, the son and son standing. Son standing Because the son in the station with the son electrical load for civilian secondary general load, not the focus of this system, so this paper focused on the object monitoring station and monitor the son of station needs detailed analysis to find the design points. According to the terminal and the son of the substation standing demand analysis, this paper for station and sons were standing as the main function of design, which is the function of automatic data collection of various standards'value of set; According to the collection value and standard setting value, which is the corresponding points of closing control, to make it meet the data collection, calculation and monitoring needs. This paper also according to the operation of the terminal and son station design, interface concise interface will be very intuitive will substation in the calculation of the data acquisition and control activities happened to reflect to attendant, in order to form good surveillance sex. This paper also for monitoring system and the child to the implementation of the terminal station, the data contrast. Through a year of operation, collect the contrast substation automation monitoring system of human management of the advantages of the relative system and necessity.Finally, this paper in qingyang carry the petrochemical projects substation automation control system transformation made to summarize, and points out that the current transformer substation automation reconstruction is still not completely solve the problem, and puts forward the prospect.
