文档介绍：工矿企业变电所运行方式优化的研究
摘要:工矿企业变电站都属于一、二级负荷,对供电系统有较高的技术经济要求,尤其煤矿变电站属于一级负荷,由于其生产条件的特殊性,首要的是保证供电的可靠与安全,并做到技术的合理,力求达到供电系统运行最经济。因此,在满足技术条件的前提下,可对供电系统运行方式进行优化。本文通过对煤矿变电站常用的8种系统运行方式,从技术和经济两方面进行分析比较找出最优的运行方式。技术方面主要从系统供电的可靠性、供电质量、短路电流的大小、接地电流、电压波动的大小,操作过电压的大小、过载能力、继电保护的复杂程度及系统操作的灵活性等方面进行比较研究;经济方面主要考虑变电站的电源线路损耗和主变压器损耗,通过综合电价,折算成年运行费用进行比较,通过以上两个方面的比较并结合申沟变电站的实际情况得出系统分裂运行方式是一种最优的运行方式,选用运行方式应优先考虑系统分裂运行。

The work mineral business enterprise changes to give or get an electric shock a research for circulating way excellently turning
Abstract: The work mineral business enterprise transformer substation belongs to a, second class carry, have to the power supply system the higher technique economy request, particularly the coal mine transformer substation belongs to a the class carries, the initial is to guarantee the power supply dependable and safety, combine to attain the technical reasonable, try hard for to attain the power supply system circulate the most economic. Therefore, at premise that satisfy the technique term next, can circulate to the power supply system the way proceed the excellent turning. This text passes to the coal mine transformer substation mon use 8 kinds of systems circulates the way, proceeding with the economic aspect from the technique parison find out the superior movement the method. The technique aspect is main from the system power supply of dependable, power supply quantity, short-circuit electric current, connect a ground of electric current, electric voltage's fluctuate, extortionate voltage in operation , ability of power despat -ch, camplicacy of protective apparatus, mobility of operation system, and so on , passing to synthesize. The power supply circuit of the main consideration in economic aspect transformer substation exhausts to exhaust with the main trans
-former, passing to synthesize to give or get an electric shock the price, breaking to calculate the adulthood movement fee proceeds parison, passing above two bine the actua
