What is a substation grounding grid?
distribution design. The main purpose of power system substation grounding grids is to maintain reliable operation and provide protection for personnel and apparatus during fault conditions. Grounding system allows controller harmonics and drain to earth the fault currents.
Why do substations need a grounding system?
It is also a key method to decrease electromagnetic interferences in substations. Considerable operation results show that, if the grounding system has not been designed suitably, then control cables will be destroyed and a high voltage will be led into the control room of the substation.
How do you determine a safe substation grounding grid?
To determine a safe substation grounding grid, it is important to compute the split factor for earth fault current including the proximity influences among the grid and the earthing systems of the incoming/outgoing transmission lines' towers.
What is a power system grounding book?
This book covers all main aspects of the grounding technologies for power systems, including sub-stations, converter stations and transmission towers. It introduces fundamental and advanced theories and technologies related to power system groundings and the research achievements of the past 20 years.
How does a grounding grid work?
A grounding grid works by controlling potential gradients on the Earth’s surface caused by high currents through the substation grid. It creates adequate ground resistance and prevents the ground potential rise (GPR) from endangering lives of people and animals nearby.
How are power stations connected to the grid?
Power stations in Canada, including those operated by the British Columbia Hydro and Power Authority (BC Hydro), are generally connected to the electrical grid. BC Hydro is a Canadian electric utility in the province of British Columbia.
