摘要
能源协调控制系统是对能源进行合理分配和利用的系统。针对公共建筑易受到耗能功率较大的装置的影响,导致供暖和制冷耗能大,无法达到节能效果的问题,文中设计一种超低能耗公共建筑能源系统协调控制系统。首先,在d-q旋转坐标系下,利用交-直变换器对外环与内环进行解耦;利用PI控制器将各种电子信号转换成数字信号,并将所收到的资料以IP形式传送至以太网。其次,通过预先自动设定的系统协调控制策略对系统配置进行自动设定,并对其进行控制和管理,计算建筑结构散热、耗能设备输出功率,依据计算结果构建总负载目标函数;再采用点与点之间的交互协议使目标函数达到最优。最后,对错误调节信号进行预处理,计算信号期望值,获取有效控制结果。通过实验验证得出,所设计系统的供暖能量节约20 J,制冷能耗节约2 J,能够达到有效控制能耗的目的。
Energy coordination and control system is the system for rational distribution and utilization of energy.Public buildings are vulnerable to the impact of devices with large energy consumption power,resulting in large energy consumption for heating and cooling,which cannot achieve the effect of energy conservation.Therefore,a coordinated control system for energy system of ultra-low energy consumption public buildings is designed.In d-q rotating coordinate system,the outer loop and inner loop are decoupled by means of AC-DC converter.The PI controller is used to convert various electronic signals into digital signals and transmit the received data to Ethernet in the form of IP.The re-set system coordinated control strategy can be used to set the system configuration automatically and control and management it,so as to calculate the output power of building structure heat dissipation and energy consuming equipment.The total load objective function is constructed according to the calculation results.Point to point interaction protocol is used to optimize the objective function.The erroneous adjustment signal is preprocessed,and the expected value of the signal is calculated,so as to obtain effective control results.The experimental results show that the designed system can save 20 J of heating energy and 2 J of cooling energy,which can effectively control energy consumption.
