名稱:CAN2000變電站綜合自動化系統(tǒng)的應(yīng)用
目前，CAN2000變電站綜合自動化系統(tǒng)已在沂南電網(wǎng)35kV張莊變電站、青駝變電站中應(yīng)用，運行2年來取得了較好的運行業(yè)績。下面我就結(jié)合該系統(tǒng)在沂南供電公司的運行情況對其性能特點、系統(tǒng)情況等幾個方面加以介紹，與大家共同交流、探討。
系統(tǒng)簡要介紹：
CAN2000變電站自動化系統(tǒng)是根據(jù)變電站自動化的發(fā)展趨勢，采用的軟硬件技術(shù)研制開發(fā)的新一代變電站自動化系統(tǒng)。完成各高壓間隔的繼電保護、遠動*、低周減載、同期操作、備用電源自投、小電流接地選線、電壓并列和切換等功能。廣泛應(yīng)用于110KV及以下電壓等級的各種變電站。
該系統(tǒng)設(shè)計、制造和試驗符合國家有關(guān)標準和IEC標準，滿足電力部有關(guān)規(guī)定及反事故措施要求。將*的電子、網(wǎng)絡(luò)、計算機技術(shù)及時應(yīng)用到變電站自動化中，使變電站的運行維護操作更加簡便實用，為促進變電站更加安全、可靠、經(jīng)濟、穩(wěn)定地運行提供良好的自動化設(shè)備。
一、系統(tǒng)性能特點
1、結(jié)構(gòu)合理：
分層分布式結(jié)構(gòu)，系統(tǒng)包含變電站層和間隔層。變電站層由當?shù)?功能、通訊控制、GPS時鐘等裝置組成。間隔層在橫向按站內(nèi)一次設(shè)備分布式配置單元，由CAx系列測控保護裝置等組成。面向?qū)ο蟮脑O(shè)計，使系統(tǒng)結(jié)構(gòu)清晰合理。
2、安全可靠：
電磁兼容性滿足IEC255-22、IEC1000-4、IEC801-5、GB/T14598、DL/T630、DL478等標準要求。系統(tǒng)中各裝置相對獨立，一個裝置故障不影響其它裝置運行。保護與測控功能相對獨立，測控及通訊網(wǎng)故障都不影響保護功能運行。
保護、測控雙CPU并行工作模式，保護CPU僅完成保護功能，測控CPU完成測控通訊及界面操作功能。CPU功能分配合理，不僅可靠性更高，同時與普通測控保護一體化裝置相比較實現(xiàn)了在單裝置內(nèi)同時滿足國家遠動、保護標準的要求。
3、使用方便：
可按用戶需求分散安裝于高壓開關(guān)柜或保護小間。
各測控保護裝置支持當?shù)厥謩涌刂萍?/span>斷路器位置顯示，保證在緊急情況下仍然有必要的信號系統(tǒng)及控制能力。測控保護裝置帶漢字液晶顯示，結(jié)合16鍵仿微機鍵盤和創(chuàng)造性的快捷菜單查詢模式，即便是*次接觸微機保護的用戶也能夠快速掌握基本操作。
保護、測控一體化設(shè)計，簡化了硬件設(shè)置和二次接線，同時又使結(jié)構(gòu)緊湊、對象對應(yīng)簡潔明了，使用維護方便。
4、技術(shù)*：
測控保護裝置內(nèi)采用搶占式實時多任務(wù)嵌入式軟件內(nèi)核和模塊化程序結(jié)構(gòu)設(shè)計。搶占式實時多任務(wù)內(nèi)核能夠保證各種任務(wù)的并行實時處理和動態(tài)切換，提高了CPU的利用效率和任務(wù)的實時性，并防止了單個任務(wù)空間中數(shù)據(jù)的偶然破壞造成的系統(tǒng)崩潰，大大提高了裝置軟件體系的穩(wěn)定性和可靠性。
獨立的保護、測控的交流電流輸入回路，測控采用了優(yōu)化的自動校準、自動跟蹤的高精度交流采樣技術(shù)，免調(diào)節(jié)、免維護、免校準，測量精度0.2級。校準參數(shù)存儲于PTCT板卡，增強了裝置間的互換性和易維護性。
系統(tǒng)提供載頻自動跟蹤技術(shù)的FSKMODEM，能自動跟蹤載頻的變化，適應(yīng)了國內(nèi)信道質(zhì)量差的條件，保證了整個系統(tǒng)的可靠通信。系統(tǒng)采用支持CSMA/CA協(xié)議的CANBus網(wǎng)絡(luò)，允許多主節(jié)點、多優(yōu)先級信息傳輸，保證信息傳輸?shù)膶崟r性。CANBus網(wǎng)絡(luò)經(jīng)濟可靠，雙絞線介質(zhì)中一根接地或任一節(jié)點故障均不影響網(wǎng)絡(luò)運行。
二、系統(tǒng)應(yīng)用簡介
1、系統(tǒng)結(jié)構(gòu)：
以張莊變電站為例，35kV進線二回，10kV母線采用單母線分段的接線方式，出線8回，其自動化系統(tǒng)結(jié)構(gòu)采用2面變壓器主保護及后備保護屏、1面35kV線路保護屏、1面10kV線路保護屏、1面后臺*和通訊管理屏。
2、網(wǎng)絡(luò)結(jié)構(gòu)：
采用*的專為強干擾環(huán)境而設(shè)計的控制局域網(wǎng)CANbus通訊網(wǎng)絡(luò)，其訪問方式為非破壞性的CSMA/CA，傳輸介質(zhì)采用雙絞線；站內(nèi)通過CC200通訊管理單元與CAX200系列測控保護裝置通訊，還可以利用串行通道與站內(nèi)其他智能設(shè)備，如電度表、直流屏、五防閉鎖系統(tǒng)通訊；通訊控制器通過串行通道與主站、當?shù)毓δ軐崿F(xiàn)通訊，上傳CAN2000系統(tǒng)及通訊采集的站內(nèi)測控保護信息，同時可接收和轉(zhuǎn)發(fā)主站、當?shù)毓δ芟逻_的各種控制和校時命令。與主站通訊采用載波通道時，可外加“MODEM+防雷盒”實現(xiàn)。
3、間隔層的智能單元：
間隔層智能單元包括35kV、10KvCAL211、CAL221線路保護裝置、CAT211、CAT212、CAT221、CAT231變壓器主保護及后備保護裝置、CAC211電容器保護裝置、CAM21X綜合*及單元測量裝置、CAB211備用電源自投、CAE211、CAE221、CAE231電壓并列裝置以及CC200通訊管理單元。各保護裝置功能相對獨立，結(jié)構(gòu)簡潔、緊湊，依賴EMC抗干擾技術(shù)和抗強震動設(shè)計，可分散安裝于高壓開關(guān)柜。保護、測控功能相對獨立，測控及通訊網(wǎng)故障都不影響保護功能運行。CPU以PHILIPS公司XA-S3單片機為核心，完成模數(shù)轉(zhuǎn)換、計算及邏輯運算等功能。CPU插件采用多層印刷板，大大提高了抗電磁*力，增強了硬件系統(tǒng)的工作可靠性。
保護、測量、控制、通訊一體化，大大簡化了硬件配置和二次接線，有效降低了PT負載，使站內(nèi)二次電纜大大簡化，節(jié)省了投資也便于維護。
4、后臺*和通訊系統(tǒng)：
變電站后臺*系統(tǒng)平臺IES-SL300采用一體化工作站，將通訊控制器、當?shù)睾笈_*功能集成于一體（也可獨立提供）。設(shè)計了更加靈活的規(guī)約處理模式，特別是提供強大的基于以太網(wǎng)TCP/IP協(xié)議的網(wǎng)絡(luò)化支持，為變電站自動化的網(wǎng)絡(luò)化應(yīng)用提供了更為優(yōu)秀的解決方案。
①系統(tǒng)特性：IES-SL300系統(tǒng)具有完備的通訊功能。能夠支持CAN網(wǎng)通訊；支持RS232/422/485方式的串行通訊；支持基于TCP/IP的以太網(wǎng)通訊；具有基本的SCADA數(shù)據(jù)采集與控制功能，能夠以圖形或表格的形式實現(xiàn)原來的一些信號屏的功能和二次設(shè)備的管理功能。
②系統(tǒng)配置：采用IN低功耗奔騰CPU,免風扇設(shè)計，以電子硬盤為系統(tǒng)實時運行存儲介質(zhì)，運行可靠，訪問速度快，抗*力強。軟件系統(tǒng)選用Windows嵌入式的產(chǎn)品，不使用虛擬內(nèi)存，特別適合無人職守的運行要求。數(shù)據(jù)庫采用ODBC或SQL編程，使用ACCESS數(shù)據(jù)庫文件格式存儲數(shù)據(jù)。基于Client/Server方式設(shè)計，便于功能擴展，選用PCAnywhere作為遠程維護軟件，功能強大。
5、CAN2000系統(tǒng)功能：
①數(shù)據(jù)量采集與處理：
裝置設(shè)計有完整的測量功能，為了保證數(shù)據(jù)量的測量精度，測量模擬量同保護模擬量是分別接入的。同時，還設(shè)計有開關(guān)量、直流模擬量、脈沖量的測量。選擇三表法或兩表法可以測量電流、電壓、有功、無功、功率因數(shù)和頻率等量。測量電流輸入同保護電流輸入獨立。裝置采用自跟蹤、自校驗、自補償、免調(diào)節(jié)技術(shù)，測量精度高。
②控制功能：
裝置操作插件可以完成跳合閘出口保持、防跳、斷路器壓力閉鎖及就地跳合閘、斷路器位置的當?shù)仫@示功能。裝置具有遠方/就地切換功能，當轉(zhuǎn)換開關(guān)放在就地位置時，將閉鎖所有的遙控功能，當切換開關(guān)放在遠方位置時，在后臺機、遠動主站的上能夠遙控斷路器跳合閘操作。
③保護信息：
自動化系統(tǒng)與微機保護進行雙向數(shù)據(jù)通信，保護裝置向系統(tǒng)傳送保護動作信號、整定值組別、運行*等信息。在當?shù)睾笈_*及和遠動主站上能夠?qū)崿F(xiàn)微機保護整定值的召喚、下發(fā)、組別切換、投/退及信號復(fù)歸等功能。
④人機會話：
以多種形式顯示變電站一次設(shè)備信息，包括：接線圖、棒圖、曲線圖、數(shù)據(jù)表等。能夠人工或自動打印圖形、報表；可以顯示遙測越限報警、遙測越限恢復(fù)、遙信正常變位、事故變位、SOE事項、遙調(diào)、遙控事項以及操作結(jié)果、操作員操作記錄等；執(zhí)行遙調(diào)、遙控操作、進行遙信、遙測量的人工置數(shù)，設(shè)置旁母替代、開關(guān)檢修、接地等標志；顯示保護信息列表，顯示母線電壓、廠站負荷等數(shù)據(jù)的實時和歷史曲線；可進行事故追憶，顯示追憶數(shù)據(jù)。
三、實際運行情況
CAN2000變電站綜合自動化系統(tǒng)具有面向?qū)ο?、分層分布等特點，該系統(tǒng)設(shè)計、制造和試驗符合國家有關(guān)標準和IEC標準，滿足電力部有關(guān)規(guī)定及反事故措施要求。將*的電子、網(wǎng)絡(luò)、計算機技術(shù)及時應(yīng)用到變電站自動化中，使變電站的運行維護操作更加簡便實用，為促進變電站更加安全、可靠、經(jīng)濟、穩(wěn)定地運行提供良好的自動化設(shè)備。其實際運行結(jié)果令人滿意，主要表現(xiàn)在以下幾個方面：
(1)、系統(tǒng)穩(wěn)定可靠，具有高度的可靠性和抗*力，未發(fā)現(xiàn)因為*系統(tǒng)負載過重或電磁干擾導(dǎo)致的網(wǎng)絡(luò)阻塞、系統(tǒng)出錯現(xiàn)象。
(2)、系統(tǒng)對異常、事故處理及時、恰當。電網(wǎng)事故時，自動推出畫面或提示信息，發(fā)出嚴重警告，并打印記錄。
(3)、實現(xiàn)了自動抄表，對電網(wǎng)運行的整點參數(shù)，自動處理儲存，定時打印報表。
(4)、通過調(diào)度主站模擬屏和調(diào)度工作站，即可完成電網(wǎng)的監(jiān)測、操作。
(5)、變電站實現(xiàn)了無人值班，四遙功能的準確無誤，為安全運行提供了保障。
四、系統(tǒng)存在的問題
CAN2000雖然是一套技術(shù)*的綜合自動化系統(tǒng)，但是在實際運行中也發(fā)現(xiàn)了一些小的缺陷，希望廠家能夠進一步完善：
(1)裝置液晶屏顯示的P、Q測量值為內(nèi)部處理值，與一次值并不對應(yīng)。
(2)在后臺機進行二次設(shè)備參數(shù)編輯后，不能同時傳送到IES-SL300管理機上，需要人工拷貝。
(3)在進行圖形編輯時發(fā)現(xiàn)，個別刀閘在IES-SL300管理機數(shù)據(jù)庫中顯示分閘，圖形仍然顯示在合閘位置。
