UNITROL 5000 模塊化 備用電流調節器特點:
產品概述
UNITROL 5000被設計成一個模塊化的“積木系統"。超過80%的系統可以由經過型式測試的系統組件制成。
這保證了更高的質量，使更短的交貨時間成為可能。電源部分由一個或多個可控硅電源變換器、交流或直流側的勵磁斷路器、勵磁閃動電路和帶撬棍的固態勵磁系統組成。
由于額外的備用電流調節器，高可用性
為了進一步增加勵磁系統的可用性，除了電壓調節器(AUTO)和勵磁電流調節器(MAN)外，還可以使用獨立的電流調節器(帶有電源、測量和門控制電路的單獨裝置)。由于對所有非活動調節器的后續控制，在活動調節器失效的情況下，可以保證平滑切換到準備操作的調節器通道。
內部ARCnet®現場總線減少布線
系統內的數據交換，例如在穩壓器、電源組件和接口設備之間的數據交換，通過串行ARCnet總線進行。
額外的接口或控制面板可以通過光鏈路定位和操作到幾千米的距離。強大可靠的電源轉換器
UNITROL 5000使用DCS 500系列緊湊型電源轉換器或UNL 13300型電源轉換器或Verithyr電源轉換器。并聯電源變換器的類型和數量是根據所需的磁場電流、上限電壓和客戶所需的占空比來確定的。
以下選項可用:
?自然或強制冷卻
?冗余風扇
?在系統運行期間(帶5極隔離器)，可以對一個電源轉換器進行維護工作。
應用程序功能塊
除了標準的軟件功能外，還可為應用程序提供各種通用的功能塊。這些是經過測試的應用程序，如輸入/輸出擴展，特定的監控功能等。
電力系統穩定器(PSS)
電力系統穩定的目的。勵磁是利用勵磁阻尼負載振蕩來提高發電機和輸電系統整體的穩定性。PSS通過影響電壓調節器的輸入來工作-對靜態勵磁系統非常有效，但對具有旋轉勵磁器的系統也有效。
ABB提供三種不同類型的電力系統穩定器:
PSS符合lEEE
對于符合ieee -PSS2A標準的穩定器，固定參數通過可調超前/滯后濾波器來實現阻尼。為了確定這些參數，ABB的計算軟件考慮了發電機和勵磁系統的數據，以及變壓器和網絡的電抗。
UNITROL 1005-0011
The UNITROL 5000 is designed as a modular “building-block system". More than 80 % of all systems can be made from type-tested system components.
This guarantees higher quality and makes shorter delivery times possible. The power section consists of one or more thyristor power converters, field breaker on the AC or DC side, the field flashing circuit and the solid state de-excitation system with Crowbar.
High availability due to the additional backup current regulator
To further increase the availability of the excitation system, in addition to the voltage regulator (AUTO) and the excitation current regulator (MAN), an independent current regulator (separate device with power supply, measurement and gate control circuits) can be used. Because of the follow-up control for all the inactive regulators, in the case of failure of the active regulator a smooth switch-over to a ready-to-operate regulator channel is guaranteed.
Less wiring thanks to the internal ARCnet® field bus
The exchange of data within the system, e.g. between the voltage regulator, power components and interface devices takes place via the serial ARCnet bus.
Additional interfaces or control panels can be located and operated up to a distance of several 1000 m via an optical link. Powerful and reliable power converters
Either compact power converters of the DCS 500 series or type UNL 13300 or Verithyr power converters are used for the UNITROL 5000. The type and the number of parallel power converters are based on the required field current, the ceiling voltage and the maximum dutycycle required by the customer.
The following options are available:
? Natural or forced cooling
? Redundant fans
? Possibility to do maintenance work on one power converter during the operation of the system (with 5-pole isolator).
Application function blocks
In addition to the standard softwarefunctions, further universally applicablefunction blocks of various kinds areavailable for the application program.These are tested application proceduressuch as input/output extensions, specificmonitoring functions, etc.
Power System Stabilizer (PSS)
The purpose of the power system stabi.lizer is to improve the stability of thegenerator and the transmission systemas a whole by using the excitation todamp load oscillations. The PSS operatesby influencing the input of the voltageregulator-extremely effective withstatic excitation systems, but also effectivefor systems with rotating exciter.
ABB offers three different types ofpower system stabilizer:
PSS in accordance with lEEE
For the stabilizer in accordance withIEEE -PSS2A, fixed parameters take careof optimum damping with adjustablelead/lag filters. To determine theseparameters ABB has calculation softwarethat takes account of the generator andexcitation system data, as well as thetransformer and network reactances.
