Photovoltaic-based alternating-current and direct-current power supply system for long-distance water delivery trunk canal engineering
A photovoltaic-based alternating current and direct current power supply system for a long-distance water delivery trunk canal project is based on the photovoltaic power generation principle and comprises a photovoltaic assembly, the photovoltaic assembly is arranged on the top face of a supporting and covering structure erected above a canal and connected with a controller, and the controller is arranged in a water delivery trunk canal gate station and provided with a plurality of output loops. The controller outputs a DC voltage and then is connected to the energy storage battery, the inverter and the plurality of DC converters. The inverter is connected with the power distribution cabinet which is connected with an external AC power supply. The external alternating-current power supply serves as a standby power supply of the system and is led from a power grid near a gate station, and when the system operates normally, the external alternating-current power supply is switched off and is switched on when detecting that a power distribution cabinet bus loses power. According to the invention, stable electric energy can be generated by completely utilizing photovoltaic power, so that an original special line power supply mode and a special direct-current power supply system of a long-distance water delivery trunk canal project are replaced. According to the invention, the requirements of zero emission and zero pollution in the long-term operation and maintenance process can be met.
一种基于光伏的长距离输水干渠工程交直流供电系统，基于光伏发电原理，包括光伏组件，光伏组件设置在渠道上方架设的支撑遮盖结构的顶面，光伏组件与控制器连接，控制器布置在输水干渠闸站内，控制器具有多个输出回路，控制器输出直流电压后分别连接到储能蓄电池、逆变器、多个直流转换器；逆变器与配电柜连接，配电柜与外来交流电源连接；外来交流电源作为本系统的备用电源，引自闸站附近电网，本系统正常运行时，外来交流电源断开，当检测到配电柜母线失电时投入。本发明可完全利用光伏产生稳定的电能，以替代长距离输水干渠工程原有的专用线路供电方式和专用直流电源系统。本发明可在长期运行及维护过程中实现零排放、零污染的要求。
