Redbud工厂位于俄克拉荷马州路德，拥有四台相同的一拖一机组，总发电能力为1.230兆瓦。该工厂于2003年开始商业，配备了来自九家不同供应商的控制装置。这种拼凑而成的控制为工厂带来了许多挑战。

OG&.E控制装置升级项目经理Khca Le表示:“我们认识到，使用多种不同的控制必然会效率低下。我们希望将这些不同的控制整合到一个的自动化平台，以所有机组的可靠性和一致性。与艾默生合作，我们在较短的时间内完成了这次重大的控制装置升级，几乎能立即感受到此次升级对产生积极影响。”

为了解决效率低下的问题，艾默生用集成的OvationTM解决方案取代了汽轮机控制装置，以及静态励磁和振动监测。此外，艾默生还对汽轮机进行了复杂的机械改造，以单点故嫜并提供更准确和快速的响应。通过升级和的汽轮机控制装置以及冗余的机械设计，汽轮机可以地达到设定值，从而将每台机组的冷启动时间缩短了25-35分钟。

The Redbud plant, located in Luther, Okla., has four identical one-tow units with a total generating capacity of 1.230 megawatts. The plant, which began commercial operations in 2003, is equipped with controls from nine different suppliers. This patchwork of controls poses a number of challenges for the plant.

Khca Le, project manager for control unit upgrades at OG&.E, said: "We recognize that using multiple different controls is necessarily inefficient. We want to integrate these different controls into a single automation platform for reliability and consistency across all units. "Working with Emerson, we completed this major control upgrade in a relatively short period of time, and the positive impact of the upgrade was felt almost immediately."

To address inefficiencies, Emerson replaced the turbine control unit with an integrated OvationTM solution, as well as static excitation and vibration monitoring. In addition, Emerson has made complex mechanical modifications to the steam turbines to provide a single point of failure 嫜 and more accurate and faster response. Through the upgraded turbine control and redundant mechanical design, the turbine can reach the set point, thereby reducing the cold start time of each unit by 25-35 minutes.
