To ensure that customers’ equipment isn’t damaged, electricity suppliers need to ensure that the voltages delivered to customers are at an even level. They achieve this by the continual monitoring of the supply equipment.
Over the last 10 years, the rapid expansion of Beijing’s underground system has helped to modernize the city. However, the sprouting metro lines would be paralyzed if the supply of electrical power was not stable. In each subway station, near one end of the platform, and sometimes in the basement, is an enclosed structure where equipment for electric power transformation is located. The purpose of these substations is to transform the voltage from the city grid into one that is used by trains.
As many energy companies seek to reduce their footprint on the environment, more efficient power and energy generation is becoming a critical issue. In the power generation and distribution market, maintenance-free power backup systems and IEC 61850-based power transmission & distribution systems improve energy generation and distribution efficiency. Power substations are subsidiaries of electricity generation systems where voltage is transformed from high to low or reversed using transformers. Nowadays, multiple protocols, including many proprietary protocols with custom communication links exist for substation automation and interoperation with devices from different vendors would be a huge advantage to users of substation automation devices.
As an alternative to fossil fuels, wind power is a plentiful, renewable, widely distributed, and clean energy as well as producing no greenhouse gas emissions during operation. Due to these characteristics, wind energy has, in recent years, become an important player in the world‘s energy markets
