2008年3月18日消息，應(yīng)用艾默生的Scenario®模擬技術(shù)，可為新發(fā)電設(shè)備項(xiàng)目和更新節(jié)省啟動時(shí)間。Con Edison ERRP項(xiàng)目的收益對此技術(shù)作了闡述，由于其意識到了減少啟動時(shí)間很重要，并且三個(gè)月的應(yīng)用已經(jīng)證實(shí)了這一點(diǎn)，所帶來的收益還包括改善的操作效能和可靠性。 ERRP——一個(gè)被縮短聯(lián)合周期的設(shè)備，在幾年前就進(jìn)入了操作領(lǐng)域，作為Con Edison東河能源集合體項(xiàng)目中主要的改善部分。該項(xiàng)目必須能維持可靠且合理的供電價(jià)格及電力供應(yīng)，服務(wù)于整個(gè)紐約市的Con Edison用戶。 ERRP設(shè)備利用兩個(gè)通用的燃?xì)廨啓C(jī)，與兩個(gè)熱恢復(fù)蒸汽發(fā)生器和一個(gè)蒸汽集電環(huán)整流器相連接。此獨(dú)特的配置將蒸汽以3.2 million lb./hr分批傳送到曼哈頓，在曼哈頓蒸汽將被用作區(qū)域加熱系統(tǒng)中的主要能源。艾默生的Ovation®技術(shù)還為此360 MW的工廠提供了許多關(guān)鍵過程控制系統(tǒng)。 Con Edison在此工廠中的大量投資使得非常關(guān)鍵的啟動變得很安全，并且試運(yùn)行也很及時(shí)。由于East River位于曼哈頓，Con Edison也必須堅(jiān)持嚴(yán)格的環(huán)境約束，如施工階段的噪音級別，以及在工廠試運(yùn)轉(zhuǎn)過程中的廢物排放等級，及啟動和操作。 為了幫助保證East River廠的最佳操作狀態(tài)，Con Edison尋找到了一個(gè)有效的培訓(xùn)員工的方法，Con Edison還希望有一個(gè)工具能幫助在其沒有安裝到工廠Ovation控制系統(tǒng)之前核實(shí)新控制邏輯。 基于二十年的行業(yè)合作關(guān)系，Con Edison與艾默生合伙提供此合適的解決方案。艾默生的Scenario模擬技術(shù)被用于監(jiān)測和控制在East River配置的獨(dú)特的新技術(shù)。 ERRP的Scenario模擬技術(shù)，由實(shí)際工廠操作軟件和完全一樣的工作站組成，此工作站可模仿East River控制室。Scenario被廣泛用于培訓(xùn)操作者，熟悉傳統(tǒng)的鍋爐/蒸汽渦輪廠的配置。通過利用艾默生的模擬技術(shù)，操作者還可以很好地變化使用微處理器，其不像先前安裝的硬線控制，使操作者能夠更快地識別，并對異常工廠過程情況做出反應(yīng)。Scenario模擬還可以被用于開發(fā)優(yōu)化操作者的使用方法，以文件形式寫成操作步驟。 [FONT=times] original text [/FONT] [font=times][Color=#708090]PITTSBURGH, PA （March 18, 2008） — Use of Emerson’s Scenario® simulation technology offers reduced plant startup time for new power facility projects and upgrades. Con Edison’s East River Repowering Project （ERRP） illustrates the gains, having realized a three month startup time reduction and ongoing benefits, including improved operational efficiency and reliability. ERRP, a truncated combined cycle facility, went into operation several years ago as part of a major improvement project at Con Edison’s East River energy complex. The project was necessary to maintain reliable and reasonably priced steam supply and electricity for Con Edison’s customers throughout New York City. The ERRP facility uses two General Electric combustion turbines connected to two heat recovery steam generators （HRSGs） and a steam ring header. This unique configuration provides steam at 3.2 million lb./hr. for dispatch into Manhattan, where it is used as a key source for the district heating system. Emerson’s Ovation® technology provides control for a number of critical processes used in this 360-MW plant. Con Edison’s significant investment in this plant made safe and timely commissioning and startup crucial. Because the East River facility is located in Manhattan, Con Edison also had to adhere to strict environmental constraints, such as noise levels during construction, as well as emissions levels during plant commissioning, startup and operation. In order to help ensure optimal operation of the East River plant, Con Edison sought a way to efficiently train their operators using equipment and plant models duplicating the repowered East River plant prior to actual commissioning and startup. Con Edison also wanted a tool to help them verify and validate new control logic prior to its installation into the plant’s Ovation control system. Based on a two-decade relationship of proven performance, Con Edison partnered with Emerson to provide the right solution. Emerson’s Scenario simulation technology was selected to monitor and control the unique processes associated with the new technology employed at the East River site. To ensure optimal plant operation, Con Edison engineers and operators teamed with Emerson to configure a high-fidelity Scenario solution. ERRP’s Scenario simulation consists of actual plant control software and duplicate workstations that mimic the East River control room. Scenario was used extensively to train operators, formerly familiar with traditional boiler/steam turbine plant configurations, on the operation of the new truncated combined cycle plant. Through utilization of Emerson’s simulation technology, operators also became well versed on using the microprocessor-based system, which unlike the previously installed hard-wired controls, enables operators to more quickly recognize and react to abnormal plant process situations. Scenario simulation was also used to develop optimum operator methodology that is documented in the plant’s operating procedures. [/color][/font]
