Load characteristics
.
Large sports center is generally a large sports complex, the entire complex includes the main stadium, comprehensive gymnasium, swimming diving hall (4000), tennis center and news center, five-star hotel, athletes village and other supporting buildings. As a modern large-scale sports venues, in order to meet the high level of sports competitions and television broadcast requirements, the venue equipped with a large number of expensive, fully functional power electronic equipment, power distribution system power quality put forward a very high demand. On the other hand, due to the large number of non-linear load of the role of electronic equipment, resulting in the electrical system in the current and voltage waveform distortion, deterioration of the power quality. In large-scale sports venues, the extensive use of power electronic equipment and components, the voltage and current waveform, is no longer a complete sine wave, but different degrees of distortion of the non-sine wave. Non-sinusoidal waves are usually synthesized from periodic electrical components.
In the theater and exhibition hall lighting mostly fluorescent lamps, large LED devices, metal halide lamps and other gas discharge type electric light source, these light sources are non-linear electrical equipment, so in operation will produce harmonics, resulting in strobe, cable heating, Communication, cable TV and other weak circuit by high-frequency harmonic interference may produce noise, or even failure.
