| Taiyuan power supply enterprise in2001in1.5square kilometers in area a feeder automation pilot modification; Since2005, according to the integrated automation system are switching station construction, and will have far easton in succession of the conditions of the switch mom access dispatching automation system.In sum up the past distribution automation practical experience and lessons, and on the basis of this topic in taiyuan in south central district a rack more mature, a equipment foundation is better, the user of the power supply reliability the demand is higher, but the power distribution automation foundation weak, the present situation of the small coverage, draw up in central south for distribution automation (with nets regulation integration support system) pilot construction. This subject mainly from three aspects. First, the implementation of existing problems of power distribution automation system; Second, power distribution automation system structure and function of the system; Third, distribution network automation implementation of properties of the analysis. One of the first research content emphatically from the "distribution network, a equipment present situation" and "distribution communication problems in the system of two aspects to research.This subject mainly do the following aspects of the creative work:1) construction independent large-scale distribution host. Master station system in the overall technology based on IEC61970/61968unified distribution network data model, design follow the system’s internal data model CIM definition. Through the main and dispatching automation system for10kV substation interface qualify real-time information and the CIM model information, and stood in the distribution model joining together, to achieve the comprehensive management in the distribution network information.2) construction collection with electronic communication type stand. Communication with electronic collection type standing achieved with the distribution terminal, power distribution master station and other intelligent device communications, will collect the information transmitted to distribution master station, distribution of the Lord will be delivered to control information distribution terminal of the function, also with the function of the monitor communications channel and the function of the distant time setting.3) with electricity integration communication platform. Power distribution automation system in the realization of each communication principle, working mode and application interface are different, integrated communication platform in power distribution in various communication way realization unified access and unified management.4) to implement the plan from the line fast. When the power distribution network fault, the master station system DSCADA collection of information analysis, judgement gives fault segment, fault isolation.To sum up, and realize the power distribution automation and control integration, can improve the power supply reliability, increase electricity, reduce line loss, reduce operation maintenance and management fees; Can improve the distribution network professional management level, strengthen the management of lean; Can reduce fault blackout time, improve the power supply service quality, enhance the enterprise social image, so as to improve the economy, management and social benefits. |
