Intelligent Gas Grid Management

autonomy成立于2015年5月，致力于开发通过优化网络压力来减少低压配电网络泄漏的技术。我们希望验证使用先进的预测分析来降低总压力，从而降低与网络压力成正比的气体泄漏。天然气（用于网络）主要由甲烷组成，甲烷是一种潜在的温室气体，天然气泄漏是全球变暖的一个重要因素。尽管全世界排放的温室气体中只有14%是甲烷，但在20年的时间里，甲烷所吸收的热量是二氧化碳的84倍。在20年的时间里，这种少量的甲烷对气候变化的影响是二氧化碳的12倍。在英国，天然气网络的泄漏量估计为7000千兆瓦时（占天然气运输量的1%），每年给消费者造成1.8亿英镑的损失，每年释放1000万吨二氧化碳当量（测量所有气体的温室效应的方法是通过与二氧化碳的比较）。通过优化压力，我们希望减少20%以上的泄漏。智能燃气管网管理（IGGM）项目将开发和测试一种预测需求和需求/压力关系的方法，自动调节网络压力，使其略高于最低水平。为了实现这一目标，我们将对拟议解决方案中最具挑战性的两个方面进行研发。数学分析大数据集开发预测软件控制模型2。一种通过机电一体化硬件设计精确调节调速器（气体压力控制阀）出口压力的方法。PoC输出将是软件，允许我们在示例天然气网络上模拟泄漏节约，以及硬件，证明可以在成本和可靠性目标范围内实现精确的调速器控制。为了取得成果，我们将与天然气分销商进行试验/商业合作，并寻求投资和资金，以开发端到端压力控制系统的原型。

Utonomy was founded in May ‘15 to develop technology for reducing leakage in low pressuregas distribution networks by optimising pressure in the network. We want to verify use ofadvanced predictive analytics to reduce overall pressure and therefore gas leakage which isdirectly proportional to the pressure in the network.Natural gas (used in the networks) is comprised largely of methane which is a potentgreenhouse gas and leakage of gas is a big contributor to global warming. Although only 14%of greenhouse gas emissions worldwide are methane, it traps up to 84 times more heat thanCO2 (over 20 years). This smaller amount of methane is 12 times worse for climate changethan CO2 over 20 years. In the UK, leakage from the gas network is estimated at 7,000 GWh(1% of gas transported) costing the consumer £180m pa and releasing 10m tonnes pa of CO2e(the method by which the greenhouse effect of all gases are measured is by comparison toCO2). By optimising the pressure, we expect to reduce leakage by more than 20%.The Intelligent Gas Grid Management (IGGM) project, will develop and test a method ofpredicting demand and demand/pressure relationships automatically regulating pressure in anetwork to keep it just above the minimum. To achieve this, we will undertake R&D on thetwo most challenging aspects of the proposed solution 1. Mathematical analysis of large datasets to develop a predictive software control model 2. A means of accurately adjusting thegovernor’s (gas pressure control valve) outlet pressure through a mechatronic hardwaredesign. The PoC output will be software that allows us to model the leakage savings on anexample gas network, plus hardware that demonstrates that precise governor control can beachieved within cost and reliability targets. To exploit outcomes, we will approach gasdistributors for trials/commercial partnerships and seek investment & funding to develop aprototype for an end-to-end pressure control system.
