Gas-Turbine and Governor Modelling and Benefits of Integrated Control of Embedded Generation Plant

建议开发燃气轮机调速器控制策略，并将其与发电机励磁控制相协调，以最大限度地提高汽轮发电机的整体贡献，改善系统的稳定性、安全性和运行。以往的研究表明，燃气轮机控制具有在配电系统环境中扩展嵌入式发电能力的潜力。该项目旨在通过燃气轮机制造商和网络运营商的参与，提供一个可靠的平台，在此平台上切实评估配电系统中燃气轮机发电的控制贡献能力。为此，初始阶段的工作将包括通过将使用MatLab和PSS/E软件包获得的仿真结果与工业合作者提供的测量测试结果进行比较来验证燃气轮机和调速器模型。随后的研究将旨在修改目前采用的燃气轮机控制理念，并将其与系统运行的要求相结合，以扩大在配电系统级别连接的燃气轮机发电厂的稳定裕度和运行范围。基于这些策略的控制方案将在相关系统运行条件下在MatLab中初步设计和测试(随后在PSS/E中应用)，以评估其鲁棒性和范围。这些研究还将旨在确定可提供的经济利益，以鼓励采用所制定的经修改的控制战略。

It is proposed to develop gas turbine governor control strategies and co-ordinate these with generator excitation control to maximise overall turbine-generator contribution to improved system stability, security and operation. Previous studies have indicated that gas turbine control has the potential for extending the capability of embedded generation in the distribution system context. This project aims to provide, through the involvement of both gas turbine manufacturers and network operators, a reliable platform from which to realistically assess the control contribution capabilities of gas turbine driven generation in the distribution system context. To this end the initial phase of the work will include validation of the gas turbine and governor model by comparison of simulation results obtained using Matlab and PSS/E software packages with measured test results provided by the industrial collaborator. The ensuing studies will aim to modify the currently adopted philosophy for gas turbine control and blend it with the requirements of system operation in a way that extends the stability margins and range of operation of gas turbine generating plant connected at distribution system level. Control schemes based on the strategies will be initially designed and tested in Matlab (and subsequently applied in PSS/E) under relevant system operating conditions to assess their robustness and scope. The studies will also aim to establish the economic benefits that may be offered as incentive for the adoption of the modified control strategies developed.
