The Study Of 380V Auxiliary Power Supply Reliability Of Bus Of Guangzhou Wanglong Thermal Power Plant

The development of modern power technology, the equipment requirements are increasing.With the increasing growth of the environmental protection industry park, the growing production capacity, Wang Lung's heating plant reliability requirements of the park is also rising.As thermal units, security and stability of each auxiliary equipment, which means security and stability of the unit, but also can ensure the stability of the industrial park users during heating.In order to better optimize the electrical equipment to complete the level of automation to ensure the auxiliary power system has high reliability, the paper of Wang Lung 380V auxiliary power plant systems for power switching device equipment type, operation and maintenance, reliability analysis and otherconduct a comprehensive analysis and evaluation, from the operation, maintenance management and reliability of the three aspects of effective measures and recommendations proposed for the 100MW power plant level Wanglong unit auxiliary power system for power switching device provides a reference model transformation.Wang long thermal power plant fast power switching device is in the original device considering the upgrading of the paper introduces the power transfer device in Wang long thermal power plant power system operation in a variety of adverse effects, including stop transmission operation, the equipment tripping, etc.for other transfer device with the power to change the power fast switching devices to provide a reference for power plants.Prepared from the cast through the power switching device to change quickly the transformation of power to ensure that the work of the unit used in the factory when the power fails, use the standby power plant safety by fast switching, ensure the unit continues to run the important auxiliary equipment.Obtained by analyzing the power fast switching devices of the renovation project has achieved good results.
