Generally, sub-Saharan countries possess abundant energy resources including renewables and fossil sources, with natural gas potentially being among the more abundant resource second only to solar power. For conventional electrical energy generation, gas turbines are one of the most prominent technologies being adopted in producing electricity from natural gas. Nigeria, for instance has the largest natural gas reserves in Africa, and the 9th largest in the World. Thus, more than 80% of her electricity generation utilizes gas turbines. To effectively monitor the state of these gas turbines, several sensors are located on the turbines to acquire data in real time. In this data article, we present the acquired data from a 5.68-MW gas turbine installed as an independent power producing unit in a community in Ogun State, Nigeria over a period of six months. Performing various descriptive analysis on the dataset, the real power measurements were taken as the target parameters, and based on a threshold correlation co-efficient of 0.5, only sixteen (16) parameters were shown to be more closely positively correlated with the real power measurements. Thus, any variation in the real power supplied by the gas turbine would have a commensurate effect on any of the other 16 parameters identified, and could thus help in troubleshooting or scheduling maintenance.
一般来说，撒哈拉以南国家拥有丰富的能源资源，包括可再生能源和化石能源，其中天然气可能是仅次于太阳能的较为丰富的资源之一。对于传统的电能生产，燃气轮机是利用天然气发电所采用的最突出的技术之一。例如，尼日利亚拥有非洲最大的天然气储量，位居世界第九。因此，该国超过80%的电力生产使用燃气轮机。为了有效监测这些燃气轮机的状态，在涡轮机上安装了多个传感器以实时获取数据。在这篇数据文章中，我们展示了一台5.68兆瓦燃气轮机在尼日利亚奥贡州一个社区作为独立发电单元运行六个月期间所采集的数据。对该数据集进行各种描述性分析后，将实际功率测量值作为目标参数，并且基于0.5的阈值相关系数，结果显示只有十六（16）个参数与实际功率测量值具有更紧密的正相关关系。因此，燃气轮机提供的实际功率的任何变化都会对所确定的其他16个参数中的任何一个产生相应影响，从而有助于故障排查或安排维护工作。
