Existing SWER lines can suffer from poor voltage regulation, difficulties with fault discrimination and the new bushfire protection schemes simply don’t work with SWER feeders.
The new DC Constant Current SWER System eliminates these problems and offers many other advantages while utilising the existing transmission line infrastructure (poles, wires & insulators) without modification. Conversion cost is significantly less than upgrading the existing AC system to solve these problems.
SWER Protection & Power Quality Improvements for the Century Ahead
Other advantages include:
No HV earthing required at individual load points.
Eliminates touch potential issues and HV earthing maintenance.
Balanced loading as seen by the 3-phase trunk line.
All 3 phases of the main line are used to derive the controlled current source for the SWER feeder
3-phase AC option at customer premises.
This removes the existing size and performance restrictions inherent with single phase motors.
Reduction in I2R losses for SWER lines running at > 70% capacity. The DC voltage can reach √2 AC voltage so only 1/√2 of the current is needed at line capacity.
Conversion of the SWER network to Mini-Grids.
DC SWER architecture supports multiple distributed energy sources & load, including net regeneration into the main AC grid. RE hosting capacity is much higher. Consumer PV inverters may be AS4777 compliant.
Reduced Utility insurance premiums.
SWER fire and other hazard risks are dramatically reduced or eliminated.
DC SWER line voltage with respect to earth reduces.
Negative voltage gradient from connection point to end of line progressively reduces the line voltage stress.
