This application claims priority based on Japanese Patent Application No. 2018-109827 filed in Japan on June 7, 2018, and the content is incorporated herein by reference.
在煤炭焚燒火力發電廠處，係設置有將煤炭粉碎並產生微粉炭的磨機(粉碎機)。磨機，係具備有藉由旋轉來將煤炭之微粒和粗粒作分離的旋轉分離機。從磨機所供給的煤炭之微粉度，係藉由旋轉分離機之旋轉數而被作控制。亦即是，若是旋轉分離機之旋轉數越高，則所供給的煤炭之微粉度係變得越高。另一方面，依存於被投入的煤炭之量以及煤炭之炭種，用以得到相同的微粉度之旋轉數係會改變。 在專利文獻1中，係揭示有因應於煤炭之投入量以及炭種來對於旋轉分離機之旋轉數作控制之技術。 [先前技術文獻] [專利文獻]In a coal-fired thermal power plant, a mill (pulverizer) that pulverizes coal and generates fine coal is installed. The mill is equipped with a rotary separator that separates fine and coarse coal particles by rotation. The fineness of coal supplied from the mill is controlled by the number of revolutions of the rotary separator. That is, as the rotation number of the rotary separator is higher, the fineness of the supplied coal becomes higher. On the other hand, the number of revolutions for obtaining the same degree of fineness varies depending on the amount of coal to be put in and the type of coal. Patent Document 1 discloses a technique of controlling the number of revolutions of a rotary separator in accordance with the input amount of coal and the type of coal.

However, even if the charcoal type of coal is specified in advance, it is difficult to grasp with good accuracy what kind of charcoal it is without actually trying to incinerate it. That is, even if it is coal belonging to the same kind of charcoal, there is a certain degree of variation in its properties (hardness, etc.), so even if it is coal of the same charcoal kind With the same control, there is also the possibility of unevenness in its micronization. The object of the present invention is to provide a control device, control system, control method and program for automatically and appropriately controlling the pulverizer according to the properties and state of coal.

輥磨機100，係在圓筒形之殼體101之上部處，具備有接受從未圖示之煤倉而來的煤炭之供給之供炭口102、和使被粉碎後的煤炭被排出之出炭口103。輥磨機100，係於殼體101之下部處而具備有載置從供炭口102所供給的煤炭之轉台104。轉台104，係藉由轉台馬達而旋轉。在轉台馬達105處，係被設置有對於輸入電流作計測之電流計111。在轉台104之上，係被設置有對轉台104作推壓之輥106。輥106，係藉由輥馬達107而旋轉。載置於轉台104上之煤
炭，係藉由被咬入至旋轉之轉台104與輥106之間，而被粉碎。
The
輥磨機100，係於轉台104之下方處，具備有使一次空氣被作吹入之空氣吹入口108。從空氣吹入口108而被吹入之一次空氣，係穿過轉台104與殼體101之間之間隙而在殼體101內被上吹。被作了粉碎的煤炭，係藉由在殼體101內而上吹之一次空氣而上升。
The
輥磨機100，係在轉台104與出炭口103之間，具備有將藉由旋轉而被粉碎了的煤炭作分級之旋轉分離機109。旋轉分離機109，係藉由分離機馬達110而旋轉。藉由一次空氣而被作了上吹的煤炭，係被導引至旋轉分離機109處，並藉由旋轉分離機109之旋轉，而被分級為較粗之粒子(粗粒)和較細之粒子(微粒)。粗粒，係落下至轉台104上，並藉由輥106而被再粉碎。另一方面，微粒，係通過旋轉分離機109，並從出炭口103而對於未圖示之燃燒裝置出炭。輥磨機100，係為微粉碎機之其中一例。

Fig. 4 is a flow chart showing the operation of the control device of the roll mill according to the first embodiment.
When the
控制裝置200，係在每解析對象時間(例如1秒)處，進行以下所示之修正量之決定處理。
首先，頻率解析部203，係將計測值記憶部202所記憶的計測值之時間序列中之最近之解析對象時間的部分時間序列讀出(步驟S1)。頻率解析部203，係藉由將所讀出的部分時間序列作頻率轉換，來得到頻率頻譜(步驟S2)。The
接著，性質狀態特定部205，係進行性質狀態記憶部204之與複數之炭種相互附加關連地而記憶的各頻率頻譜與在步驟S2中所得到的頻率頻譜之間之形態匹配，並特定出類似度為最高之炭種(步驟S3)。Next, the property
性質狀態變化判定部206，係將計測值記憶部202所記憶的計測值之時間序列中之關連於最近之解析對象時間之第1部分時間序列和關連於第1部分時間序列之起點以前的解析對象時間之第2部分時間序列讀出(步驟S4)。亦即是，在將現在時刻設為T0，並將解析對象時間設為t的情況時，第1部分時間序列，係身為從時刻T0-t起直到時刻T0為止的計測值之時間序列，第2部分時間序列，係身為從時刻T0-2t起直到時刻T0-t為止的計測值之時間序列。第1部分時間序列，係等同於成為頻率解析部203之解析對象之部分時間序列。
性質狀態變化判定部206，係算出第1部分時間序列與第2部分時間序列之間之在各取樣時序的每一者處之偏差之累積(步驟S5)。亦即是，性質狀態變化判定部206，係算出根據第1部分時間序列所特定出之波形與根據第2部分時間序列所特定出之波形之間之差分面積。The property state
性質狀態變化判定部206，係判定所算出的偏差之累積是否身為特定之臨限值以上(步驟S6)。性質狀態變化判定部206，當判定偏差之累積係身為特定之臨限值以上的情況時(步驟S6，YES)，係判定被投入的煤炭之炭種係有所變化。另一方面，性質狀態變化判定部206，當判定偏差之累積係身為未滿臨限值的情況時(步驟S6，NO)，係並不判定被投入的煤炭之炭種係有所變化。亦即是，由於就算是當性質狀態特定部205所特定出的炭種係為與前一次所特定出之炭種相異的情況時，也可能會有此係身為偶發性之變化(例如，由石頭等之異物之混入所導致的變化)的可能性，因此，有鑑於此，性質狀態變化判定部206，當前一次與此次之計測值之波形之差為小的情況時，係並不判定為煤炭之炭種有所變化。The property state
當性質狀態變化判定部206判定偏差之累積係為臨限值以上的情況時(步驟S6，YES)，修正值決定部207，係將性質狀態記憶部204之與性質狀態特定部205所特定出的炭種相互附加關連地所記憶之修正函數讀出(步驟S7)。修正值決定部207，係算出性質狀態記憶部204之與被特定出之炭種相互附加關連地而記憶的頻率頻譜與在步驟S2中所得到的頻率頻譜之間之偏差之累積(步驟S8)。修正值決定部207，係藉由將所算出的偏差之累積代入至修正函數中，而得到轉矩指令修正值(步驟S9)。When the property state
另一方面，當性質狀態變化判定部206判定偏差之累積係身為未滿臨限值的情況時(步驟S6，NO)，修正值決定部207，係將前一次所決定的轉矩指令修正值決定為此次之轉矩指令修正值(步驟S10)。On the other hand, when the property state
藉由以上之處理程序，控制裝置200，係能夠決定針對轉矩指令取得部208所取得的基礎轉矩指令之轉矩指令修正值。之後，修正部209，係在每次轉矩指令取得部208取得基礎轉矩指令時，對於基礎轉矩指令加算所決定的轉矩指令修正值，來對於轉矩指令作修正，控制部210，係藉由將被修正後的轉矩指令對於分離機馬達110作輸出，而對於輥磨機100作控制。轉矩指令，係為控制訊號之其中一例。With the above processing routine, the

如此這般，第1實施形態之控制裝置200，係將輥磨機100之轉台馬達105之輸入電流之計測值，以至少轉台馬達105之電源電流之頻率以上之頻率來取得之，並基於該計測值之時間序列，來對於輥磨機100輸出控制訊號。如同圖2中所示一般，轉台馬達105之輸入電流之頻率頻譜，由於係以轉台馬達105之電源電流之頻率為中心而擴展，並依存於煤炭之炭種而有所相異，因此，控制裝置200，係藉由使用以轉台馬達105之電源電流之頻率以上的頻率所取得之計測值之時間序列，而能夠因應於煤炭之性質狀態來自動性且適當地對於粉碎機作控制。"Effect"
In this way, the
又，第1實施形態之控制裝置200，係藉由計測值之時間序列之頻率解析，來特定出頻率頻譜，並基於此來對於輥磨機100輸出控制訊號。頻率頻譜，相較於計測值之時間序列，在分析處理中係並不會受到起因於瞬間性之變化所導致的影響。另一方面，計測值之時間序列，相較於頻率頻譜，在分析處理中係容易檢測出瞬間性之變化。Moreover, the
又，第1實施形態之控制裝置200，係基於計測值之時間序列之歷時性之變化，來判定煤炭之炭種的變化之有無。藉由此，控制裝置200，藉由就算是在發生有起因於石頭等之異物之混入所導致的偶發性之輸入電流波形之變化的情況時，當與過去之計測值之波形之差為小的情況時，亦並不判定為存在有煤炭之炭種之變化，係能夠防止錯誤判定為煤炭之炭種有所變化的情形。Moreover, the
又，第1實施形態之控制裝置200，係基於頻率頻譜來特定出煤炭之炭種，並基於計測值之時間序列來判定煤炭之炭種的變化之有無。亦即是，控制裝置200，係將頻率頻譜以及計測值之時間序列在炭種之特定和炭種之變化之判定中分別使用相異者。如此這般，藉由使用頻率頻譜以及計測值之時間序列之雙方，控制裝置200，係能夠更為穩健(robust)地推測煤炭之炭種。Furthermore, the
