... of gas distribution systems as California works to reduce gas carbon emissions by electrifying buildings. 2 Introduction and Background A planning engineer’s role is to perform hydraulic analysis of pipeline networks. Hydraulic analysis rarely only requires 1 or 2 simulation runs to meet...

... is mostly based on the different versions of the CEPEI Methodology Manual [2]. However, the approach has to be refined and adapted to the reality of the GM distribution system. For obvious reasons, it is desirable to obtain a more realistic flow rate, which can be noticeably smaller than the one predicted...

... ABSTRACT This paper will focus on the utilization of advanced pipeline simulation software to proactively identify and rank distribution regulator stations based on their criticality to meet customer demand in an interconnected distribution system. A particularly complex distribution network...

... to support the system. Figure 1 illustrates how the Santa Cruz Area system would be impacted by the project. A number of distribution systems would require PNG support during this clearance. The largest distribution system in the area is the Santa Cruz 50 psig HIS which is normally supplied by 11 DR stations...

... Abstract This paper will present actual use cases of batch analysis technology using PG&E's Batch Analysis Tool (BAT) on gas distribution systems. This paper supplements the PG&E paper Pipeline Simulation Modeling Advancements - Numerous Scenarios Analyzed Simultaneously. PG&E...

Due to the rare occurrences...

... ABSTRACT: Geographic Information Systems (GIS) and Computer Aided Drawing (CAD) applications are used by many Natural Gas Utilities to maintain information about the facilities in their gas distribution systems. This data is often the same or similar to the information required to build...

... process was initiated with the following objectives: reduce the loading time; and improve simulation accuracy. PG&E Gas Transmission and Distribution Systems The PG&E gas system serves over 3.7 million gas customers in northern and central California from the Oregon-California border...

... systems. 1. Introduction OMV's aas transnortation system: OMV operates a national distribution system as well as two international transmission systems (see Fig. 7). Gas is moved from external sources, few domestic fields, 5 storage fields, through 800 miles of pipelines, 10 compressor stations...

..., is widely used in Poland for analysis and simulation of gas distribution systems. In contrast, there has been comparatively little research interest into the development of methodologies aimed at optimising the design of pipe networks. There are very few computer packages available for commercial use...

... with the requirement for a tool to analyze alternatives in this changing environment, Illinois Power turned to Energy Management Associates' SENDOUT software system. SENDOUT gives Illinois Power the ability to describe its distribution system in detail and assess the impacts of various scenarios on system operations...

... INTRODUCTION Two-phase flow is the simultaneous flow of liquid and gas in the same pipe, duct, or channel. This paper is concerned with transient two-phase flow in pipes, as occurs in gathering, transmission, or distribution systems or in steam pipes. Two-phase flow has generally been of more...

... ABSTRACT Transient flow in low pressure distribution systems presents special problems to the distribution engineer if computer control is anticipated. Modeling low pressure transient flow requires more work than setting up pipeline problems. Transient problems in low pressure systems were...
