Efficient modelling of natural gas pipeline on electromagnetic transient simulation programs

Electromagnetic transient programs (EMTPs) are widely used for simulating electromagnetic in power systems. With the increasing interest integrated energy system (IES), it would be beneficial to extend scope of EMTP-type application multi-physics transients electrical and gas networks. An efficient accurate model pipeline is proposed EMTP simulation pneumatic transients. The split into a number segments using spatial discretization. Analogies between electric quantities, such as flow pressure, current, voltage, create circuit representation pipe segment. represented by distributed-element model. In order enhance computational efficiency, nodal equation reformulated. appears two-port Norton equivalent with constant admittances. Case studies performed demonstrate accuracy efficiency implementation program systems computer aided design (PSCAD) enables analysis diverse (IEGSs).
