背景技术 Background technique
当前，随着电子技术的发展，工厂的许多设备实时反应速度越来越快，设备精度越来越高，伴随着设备仪器的高性能，工厂设备对用电质量也越来越高。与此同时，工厂、企业中大量非线性负载的使用，使得工厂电网中谐波污染也越来越严重。而电力系统谐波的危害也是显而易见的：增加输电、供电和用电设备的额外附加损耗；影响继电保护和自动装置的工作可靠性；对通讯系统工作产生干扰；对用电设备的正常工作产生影响。 At present, with the development of electronic technology, the real-time response speed of many equipment in the factory is getting faster and faster, and the precision of the equipment is getting higher and higher. With the high performance of equipment and instruments, the quality of power consumption of factory equipment is also getting higher and higher. At the same time, the use of a large number of nonlinear loads in factories and enterprises makes the harmonic pollution in the factory power grid more and more serious. The harm of harmonics in the power system is also obvious: increase the additional loss of power transmission, power supply and electrical equipment; affect the reliability of relay protection and automatic devices; interfere with the work of communication systems; normal work of electrical equipment make an impact.
通常，工厂企业在进行系统供电时，为保证供电远端设备的正常供电，一般会采取过压供配电，而过剩的电压供给，不但造成了极大的电能消耗，还会影响终端用电设备的安全使用，从而影响设备的使用寿命。 Usually, when factories and enterprises provide system power supply, in order to ensure the normal power supply of remote equipment, they generally adopt overvoltage power supply and distribution, and the excess voltage supply not only causes a huge power consumption, but also affects the terminal power consumption. The safe use of the equipment will affect the service life of the equipment.

具体实施方式 Detailed ways
本电能质量优化装置，连接与电网电源和用电设备之间，其特征在于，包括：输入采样回路电路板和供电输出回路电路板；所述输入采样回路电路板分别与电流电压分析回路电路板、功率因数分析回路电路板、谐波分析回路电路板、HMI及工作设定输入单元连接中央处理单元。 The power quality optimization device is connected between the grid power supply and the electrical equipment, and is characterized in that it includes: an input sampling circuit board and a power supply output circuit board; the input sampling circuit board is connected with the current and voltage analysis circuit board respectively The power factor analysis circuit board, the harmonic analysis circuit board, the HMI and the work setting input unit are connected to the central processing unit.
其中，所述中央处理单元有优化控制单元与滤波控制单元构成，所述中央处理单元上端连接自动旁路控制回路电路板，其下端连接有输出采用反馈回路电路，其右端连接功率优化调整装置、滤波伺服装置、输出显示回路电路板、报警故障输出回路电路板，所述功率优化调整装置与滤波伺服装置连接于供电输出回路电路板，供电输出回路电路板与输出采集反馈回路电路板连接。接通电能质量优化装置的输入电源，这时红色指示灯亮，表示电路有电。 Wherein, the central processing unit is composed of an optimization control unit and a filter control unit, the upper end of the central processing unit is connected to an automatic bypass control loop circuit board, the lower end is connected to an output feedback loop circuit, and the right end is connected to a power optimization adjustment device, The filter servo device, the output display circuit board, and the alarm fault output circuit board, the power optimization adjustment device and the filter servo device are connected to the power supply output circuit board, and the power supply output circuit board is connected to the output acquisition feedback circuit board. Connect the input power of the power quality optimization device, then the red indicator light is on, indicating that the circuit has power.
转换开关SA1起选择工作模式的作用：旁路模式、停止模式、优化模式。所述旁路模式，直接输出电网电压，没有优化功能；所述停止模式，输出电压为零；所述优化模式，分为自动优化模式和手动优化模式。 The transfer switch SA1 plays the role of selecting the working mode: bypass mode, stop mode, optimization mode. In the bypass mode, the grid voltage is directly output without optimization function; in the stop mode, the output voltage is zero; in the optimization mode, there are automatic optimization mode and manual optimization mode.
旁路运行（非优化）只需将转换开关SA1打在旁路档位，这时黄色指示灯亮。在自动优化模式下运行时，当电网电压高于260V或者低于180V时，也将自动切换到旁路；这时绿色指示灯熄灭，黄色指示灯亮，蜂鸣器发出警报。 Bypass operation (non-optimized) only needs to turn the transfer switch SA1 on the bypass gear, and the yellow indicator light will be on at this time. When running in automatic optimization mode, when the grid voltage is higher than 260V or lower than 180V, it will also automatically switch to bypass; at this time, the green indicator light is off, the yellow indicator light is on, and the buzzer sounds an alarm.
转换开关SA2起选择优化控制方式的作用。手动控制方式：先将转换开关SA2打到手动控制，再将转换开关SA1打到优化档位，系统就将工作在手动控制优化模式下；这时可以通过转换开关SA3选择优化档位。自动控制方式：先将转换开关SA2打到自动档位，再将转换开关SA1打到优化模式系统就将工作在自动控制节电模式下。 Change-over switch SA2 plays the role of selecting optimal control mode. Manual control mode: first turn the transfer switch SA2 to manual control, and then turn the transfer switch SA1 to the optimal gear, and the system will work in the manual control optimal mode; at this time, the optimal gear can be selected through the transfer switch SA3. Automatic control mode: first turn the transfer switch SA2 to the automatic gear, and then turn the transfer switch SA1 to the optimization mode, and the system will work in the automatic control power-saving mode.
手动控制时，优化模式可一次性设定完成，重新切换时，一定要先将转换开关SA1打在停止档，再调整。 In the case of manual control, the optimization mode can be set at one time. When switching again, the switch SA1 must be set to the stop position first, and then adjusted.
