NEPLAN Electricity is described as 'software tool to analyse, plan, optimize and simulate networks. The user-friendly graphical interface allows the user to perform study cases very efficiently'. There are six alternatives to NEPLAN Electricity for Windows and iPhone. The best alternative is DOC, which is free. Other great apps like NEPLAN Electricity are NAP - Network Analysis and Planning (Paid), PowerFactory (Paid), PSS/E (Paid) and ETAP (Paid).
DOC is a software dedicated to the design and calculation of single-line diagrams of electrical systems in low and medium voltage, allowing the user to choose switching devices and security, and for verification and coordination of protective devices.
NAP is a software for analysis and planning of electrical networks including Load Flow (ILF), Load Flow with constraints (CPF), Optimized Load Flow (OPF), Short circuit calculation (SCC), Incident simulation (OUTSIM), Stability calculation (STABIL).
Vision Network Analysis is a program for the planning, design and management of electricity networks. The package can very easily carry out load flow and short-circuit calculations as well as fault and reliability analyzes.
