Low-voltage electrical networks often experience excessive voltage losses and drops, particularly due to phase imbalances. Distributors need to differentiate between issues caused by these imbalances and those resulting from insufficient network sizing. They must then assess the cost-effectiveness of balancing and reinforcement measures to prioritize and make informed decisions about their projects. REBAN (Reduction of Losses by Balancing Network) is designed to assist distributors throughout this process.
REBAN offers all the standard functions of low-voltage network calculation software. Based on a detailed or generalized description of the network and its loads (either individualized or distributed linearly), REBAN provides insights into transit margins, voltage drops, their severity, and losses, all presented through color-coded graphs or tables.
REBAN also includes the following special features:
- Calculation for two- or three-phase Networks: Includes support for distributed neutral networks with adjustable impedance.
- Adaptable Inputs: Tailors inputs based on the precision of available data.
- Load Characterization: Allows for manual or automatic categorization of loads based on their peak contribution.
- Phase Imbalance Consideration: Accounts for imbalances between phases.
- Load Switching Proposals: Suggests shifting loads from one phase to another to improve balance.
- Profitable Reinforcement Proposals: Recommends cost-effective network reinforcements with valuation.
- Economic Profitability Analysis: Calculates the profitability of proposed balancing and reinforcement measures based on economic parameters.
- Synthetic Results Presentation: Offers a summary of results for different network states: “initial,” “balanced,” and “balanced and reinforced.”
REBAN is ideally suited for the quick assessment of investments needed to address significant voltage losses or drops. It employs an efficient load balancing algorithm and is designed to be user-friendly, requiring no prior expertise in low-voltage network calculations.
