【摘要】：现代智能楼宇系统的供配电系统，既能获得来自电网的电能注入，也能通过自身的微网系统完成部分电能的自给供应，并可能在富余和外部软硬件适宜的情况下完成向电网的电能输送。搭建智能化的供配电监控系统，能够及时预警故障、并对重要故障进行应急处理，减少电力维护人员的工作量、提高供电的可靠性。在论文中，我们以某建筑的供配电系统为雏形，搭建了智能楼宇配电监控系统的监控模型，同时完成了在公共照明区域引入单相光伏逆变发电系统的实验论证。智能楼宇配电监控系统中，我们以S7-300系列PLC（CPU315-2DP）作为控制核心、CP343-1作为工业以太网通信单元完成了对现场仪表信号的采集、电流保护、火灾报警处理、电容柜投切、自备发电机投切的智能控制，在PLCSIM中进行了硬件仿真测试。以WinCC6.0作为上位机组态软件，完成了上位机监控画面的设计，实现了电参量的实时监控、报警记录查询。公共照明区域引入单相光伏逆变发电系统的设计。我们对所设计的硬件电路进行了仿真测试，硬件测试。其中硬件部分包括：主功率逆变电路、电参量采样电路、以DSP28335为控制核心的控制电路；软件部分包括SPWM生成、ADC信号采样、故障报警、错误信号捕获单元以及频率捕获单元等程序。
[Abstract]:The power supply and distribution system of the modern intelligent building system can not only obtain the electric energy injection from the power grid, but also complete the self-supply of part of the electric energy through its own micro-grid system. And it is possible to complete the power transmission to the power grid with surplus and suitable external hardware and software. Building an intelligent power supply and distribution monitoring system can timely warn the faults, deal with the important faults, reduce the workload of the power maintainers, and improve the reliability of the power supply. In this paper, we take the power supply and distribution system of a building as the prototype, and build the monitoring model of the intelligent building distribution monitoring system. At the same time, we have completed the experimental demonstration of the introduction of single-phase photovoltaic inverter power generation system in the public lighting area. In the intelligent building distribution monitoring system, we use S7-300 series PLCU CPU315-2DP) as the control core, CP343-1 as the industrial Ethernet communication unit to complete the field instrument signal collection, current protection, fire alarm processing, capacitor cabinet switching. The intelligent control of on-off of self-provided generator is tested by hardware simulation in PLCSIM. Taking WinCC6.0 as the configuration software of the upper computer, the design of the monitor screen of the upper computer is completed, and the real-time monitoring of electric parameters and the query of alarm record are realized. Design of single-phase PV Inverter system in Public Lighting area. We have carried on the simulation test to the designed hardware circuit, the hardware test. The hardware part includes: main power inverter circuit, electric parameter sampling circuit, control circuit with DSP28335 as the control core, software part including SPWM generating SPWM signal sampling, fault alarm, Error signal acquisition unit and frequency acquisition unit and other programs.
