低諧波電源品質控制系統及其方法Low harmonic power quality control system and method thereof

本發明是有關於一種低諧波電源品質控制系統及低諧波電源品質控制方法，特別是有關於具減少諧波功能的低諧波電源品質控制方法，以比例方式於連續輸出時間間隔輸出全功率驅動電壓，並於連續不輸出時間間隔停止輸出全功率驅動電壓。The invention relates to a low harmonic power quality control system and a low harmonic power quality control method, in particular to a low harmonic power quality control method with a harmonic reduction function, which outputs a full scale at a continuous output time interval in a proportional manner. The power drives the voltage and stops outputting the full power drive voltage at continuous output time intervals.

大部分的電源品質控制系統中，多數都是以非對稱輸出所需要的功率為主，常用的方法為分配式零位控制與直線式相位控制。此兩種控制方式是以全波為單位或是以半波為單位之輸出驅動電壓。請參閱第1~3圖，以分配式零位控制為例，最高驅動電壓中斷頻率之狀態為當驅動電壓輸出功率為百分之五十時(第2圖)，此時中斷頻率為輸出交流電頻率之二分之一。請參閱第4~6圖，以直線式相位控制為例，當非全功率運轉輸出時，輸出驅動電壓為每正負半週切相角電壓大小作為電壓輸出大小變化。現行的方法皆有諧波產生過多之現象。Most of the power quality control systems are based on the power required for asymmetric output. The commonly used methods are distributed zero control and linear phase control. The two control methods are output voltages in units of full waves or in half wave units. Please refer to the first to third figures. Take the distributed zero control as an example. The state of the highest driving voltage interrupt frequency is when the driving voltage output power is 50% (Fig. 2). At this time, the interrupt frequency is output AC. One-half of the frequency. Please refer to the 4th to 6th figures. Take the linear phase control as an example. When the output is not full power, the output drive voltage is the voltage of the phase-cut angle of each positive and negative half-cycle as the voltage output size change. The current methods all have excessive harmonic generation.

然而電力調整裝置輸出之驅動電壓目前都是以正負半週切相角的方式輸出或隨著驅動電壓不斷的中斷輸出，此電路中會形成大量的諧波干擾，進而造成設備損壞。因此不論對於電子設備本身的使用壽命或是為了增進設備的使用效率皆為亟欲解決之問題。However, the driving voltage outputted by the power regulating device is currently outputted in a positive or negative half-cycle phase-cut angle or continuously interrupted with the driving voltage, and a large amount of harmonic interference is formed in the circuit, thereby causing equipment damage. Therefore, whether it is for the service life of the electronic device itself or for improving the efficiency of using the device, it is a problem to be solved.

有鑑於上述習知技術之問題，本發明之目的就是在提供低諧波電源品質控制方法，以解決諧波所產生的問題。In view of the above problems of the prior art, the object of the present invention is to provide a low harmonic power quality control method to solve the problems caused by harmonics.

請參閱第9~11圖，其係為本發明之驅動電壓輸出圖，其說明在各種不同的驅動電壓下所形成的波形。圖中，有輸出全功率驅動電壓為全黑之波形，停止輸出全功率驅動電壓為鏤空的波形。以第9圖為例，每時間間隔具有100個週期存在時，當功率輸出為10%，可看出只有10個週期有全功率驅動電壓，其餘90個週期為停止輸出全功率驅動電壓。以第10圖為例，當功率輸出為50%，會先出現50個週期全功率驅動電壓，其餘50個週期為停止輸出全功率驅動電壓。以第11圖為例，當功率輸出為90%，會先出現90個週期全功率驅動電壓，其餘10個週期為停止輸出全功率驅動電壓。如此一來每個單位時間內只有一次輸出全功率驅動電壓到停止輸出全功率驅動電壓之改變。至於連續輸出時間間隔與連續不輸出時間間隔之設定，此控制器具有多組單位時間可選擇。Please refer to FIGS. 9-11, which are driving voltage output diagrams of the present invention, which illustrate waveforms formed at various driving voltages. In the figure, there is a waveform in which the output full-power driving voltage is all black, and the output of the full-power driving voltage is stopped. Taking Figure 9 as an example, when there are 100 cycles per time interval, when the power output is 10%, it can be seen that only 10 cycles have full power driving voltage, and the remaining 90 cycles are to stop outputting full power driving voltage. Taking Figure 10 as an example, when the power output is 50%, 50 cycles of full-power drive voltage will appear first, and the remaining 50 cycles will stop outputting full-power drive voltage. Taking Figure 11 as an example, when the power output is 90%, 90 cycles of full-power drive voltage will appear first, and the remaining 10 cycles will stop outputting full-power drive voltage. In this way, only one output of the full power drive voltage per unit time is output to stop the output full power drive voltage change. As for the continuous output time interval and the continuous non-output time interval setting, this controller has multiple sets of unit time selectable.

請參閱第12圖，其係為本發明之低諧波電源品質控制方法之實施步驟流程圖。此低諧波電源品質控制方法包含下列步驟：在步驟S10中，利用偵測裝置接收至少一回饋訊號，並將各回饋訊號分別轉換為控制訊號。Please refer to FIG. 12, which is a flow chart of the implementation steps of the low harmonic power quality control method of the present invention. The low harmonic power quality control method includes the following steps: in step S10, the detecting device receives at least one feedback signal, and converts each feedback signal into a control signal.

在步驟S20中，利用電力調整裝置於第一時間間隔內接收各控制訊號並計算出各控制訊號之平均值。In step S20, the power adjustment device receives each control signal in a first time interval and calculates an average value of each control signal.

在步驟S30中，利用電力調整裝置於第二時間間隔內輸出依據平均值的驅動電壓，並依據平均值分配連續輸出時間間隔與連續不輸出時間間隔之比例，以於連續輸出時間間隔連續輸出全功率驅動電壓，並於連續不輸出時間間隔停止輸出全功率驅動電壓。In step S30, the driving voltage according to the average value is outputted by the power adjusting device in the second time interval, and the ratio of the continuous output time interval to the continuous non-output time interval is allocated according to the average value to continuously output the full output at the continuous output time interval. The power drives the voltage and stops outputting the full power drive voltage at continuous output time intervals.

在步驟S40中，利用阻性負載裝置接收驅動訊號，而進行對應運作，且根據阻性載裝置之特性產生回饋訊號。In step S40, the driving signal is received by the resistive load device, and the corresponding operation is performed, and the feedback signal is generated according to the characteristics of the resistive carrier device.

請參閱表1，其為以比例方式於連續輸出時間間隔輸出全功率驅動電壓，並於連續不輸出時間間隔停止輸出全功率驅動電壓的情況下諧波佔均方根(Root Mean Square，RMS)與基本波之比例。當以百分之三十的驅動電壓運作時佔均方根百分比之總諧波失真為2.91%，佔基本波百分比之總諧波失真為2.92%。當以百分之五十的驅動電壓運作時佔均方根百分比之總諧波失真為3.24%，佔基本波百分比之總諧波失真為3.24%。請參閱表2，其為在分配式零位控制法的情況下諧波佔均方根與基本波之比例。當以百分之三十的驅動電壓運作時佔均方根百分比之總諧波失真為18.81%，佔基本波百分比之總諧波失真為18.36%。當以百分之五十的驅動電壓運作時佔均方根百分比之總諧波失真為18.74%，佔基本波百分比之總諧波失真為18.37%。由兩個表格的數據中可以輕易看出，以比例方式於連續輸出時間間隔輸出全功率驅動電壓，並於連續不輸出時間間隔停止輸出全功率驅動電壓的情況之下，諧波大量的減少，可見實驗與理論相符。Please refer to Table 1, which is to output the full power driving voltage in a proportional manner at the continuous output time interval, and to stop the output of the full power driving voltage continuously without outputting the time interval, the harmonics occupy the root mean square (Root Mean Square, RMS) The ratio to the basic wave. When operating at 30% of the drive voltage, the total harmonic distortion as a percentage of the root mean square is 2.91%, and the total harmonic distortion as a percentage of the fundamental wave is 2.92%. When operating at 50% of the driving voltage, the total harmonic distortion as a percentage of the root mean square is 3.24%, and the total harmonic distortion as a percentage of the fundamental wave is 3.24%. Please refer to Table 2, which is the ratio of the harmonics to the root mean square and the fundamental wave in the case of the distributed zero control method. When operating at 30% of the driving voltage, the total harmonic distortion as a percentage of the root mean square is 18.81%, and the total harmonic distortion as a percentage of the fundamental wave is 18.36%. When operating at 50% of the driving voltage, the total harmonic distortion as a percentage of the root mean square is 18.74%, and the total harmonic distortion as a percentage of the fundamental wave is 18.37%. It can be easily seen from the data of the two tables that the full-power driving voltage is output in a proportional manner at the continuous output time interval, and the harmonics are greatly reduced in the case where the continuous output of the full-power driving voltage is stopped continuously without outputting the time interval. It can be seen that the experiment is consistent with the theory.
