Hao Tian Group Cogeneration Electrical Design

With the rapid development of the national economy, and the resultingenvironmental pollution should not be underestimated. As we all know, high-energyindustry is highly polluting enterprises, coal, for example, in the processing andutilization of coal and ore mining process will produce a lot of waste rock-gangue. HaoTian Lan carbon annually in the production process and wash the coal preparation plantwill produce about70million t of coal gangue,1,000,000t of coke powder,44000t slimeresidue3000t. In addition to the use of outer parts of coke powder, a subsidiary productgangue, coal, residual oil and so there is no user, the basic long-term pile, both resultingin a waste of resources, but also caused environmental pollution area. According to thestatus Hao Tian Group, the construction of2×220t/h high temperature and pressure toburn coal gangue based circulating fluidized bed boilers and2×50MW extractioncondensing steam turbine generators and related auxiliary facilities. Hao Tian Group toaddress low calorific value fuel nowhere digestive problems.The subject completed the design from reality main electrical wiring, wiring and DCauxiliary power system wiring and other engineering programs; after electrical wiringdetermined to study the short-circuit current is calculated based on the distributioncoefficient; to circuit breakers, current transformers as an example, the electricalequipment for a dynamic and thermal stability of the check; to study the protectionconfiguration and setting calculation principle, combined with practical engineering,respectively, for the protection and the protection of the auxiliary power generatortransformer group were setting calculation; for the main electrical wiring problemsencountered Hao Tian engineering, relay malfunction breaker tripping and some practicalproblems, starting from the theory and the practice, given the appropriate solution foreach problem.
