发电机组并机柜Generator set and cabinet

并机柜,亦称发电机自动控制柜,当两台及以上发电机组联合在一起向负荷供电时,或者当一台或多台发电机组联合在一起向电网供电时,需要加装发电机并机/并网柜,系统才能达到联合供电的要求,使发电机正常工作。
And cabinet, which is also called "generator automatic control cabinet", when two or more generators supply power to load together, or when one or more generators together to the grid power supply, the need to install the generator weaver/grid cabinet, the system can achieve joint power supply requirements, make the normal work of the generator.

Automatic average active load and unbalanced load ratio adjustment;

6.自动频率跟踪;
水果拉霸多人版Automatic frequency tracking;

7.逆功率、超功率检测及报警停机保护;
水果拉霸多人版Reverse power and overpower detection and alarm stop protection;

8.机组短路及过流保护;
Short circuit and overcurrent protection of the unit;

9.自动同步检测,自动同步合闸、自动并车;
水果拉霸多人版Automatic synchronous detection, automatic synchronous closing, automatic    shut-off;

10.市电自动充电及充电失败报警功能;
The alarm function of automatic charging and failure of charging;

11.有功和无功负载的无差分配;
水果拉霸多人版Undifferentiated distribution of active and reactive loads;

12.BINGLIEWEIRUANJIAZAI,JIELIEWEIRUANXIEZAI(FUHEZHUANYIHOUCAIJIELIEFENZHA);

13.当电力故障信号送到并机柜系统,系统接受到此信号,机组按设定程序优先启动某机组、机组自检,并加速到额定的速度及建立电压,检出其中1台达到设定值后投入总线,后机组经自动同步控制陆续投入总线并联运行(启动信号为前机组故障或满负荷后),同时自动分担负载;
水果拉霸多人版When the power fault signal to and cabinet system, the system receives the signal, the unit according to the priority setting program start one unit and the unit self-check, and accelerated to the rated speed and voltage,detection of 1 after reaching set value into the bus, after the unit by the automatic synchronization control their bus parallel operation (start signal for the fault before or after full load), automatic Shared load at the same time;

14.当任何1台机组出现故障时,后备机组自动启动运行,故障机组自动停机,同时发出警报;
When any one unit fails, the backup unit will start operation automatically, and the fault unit will stop automatically, and an alarm will be issued at the same time.

15.当市电电力正常后,市电送电所有机组的断路器经控制系统控制全部分闸,机组进入无载冷却怠速状态,冷车时间到达,所有机组停止运转,恢复自动待命状态;
水果拉霸多人版When mains power is normal, the mains power all circuit breaker of the unit by the brake control system to control the whole part, into the no-load cooling unit idle state, cold car time, all units to stop operation, restore automatically on standby;

要求条件 Demand conditions

水果拉霸多人版1、DIANYAXIANGDENG;Equal voltage;

水果拉霸多人版2、PINLVXIANGDENG;The same frequency;

水果拉霸多人版3、XIANGXUYIZHI;The phase sequence is consistent;

水果拉霸多人版4、XIANGWEIXIANGDENG;Equal phase;

优点 advantages

1、提高供电系统的可靠性、连续性。因为多机组并联成一个电网,供电的电压和频率稳定,可以承受较大负荷变化的冲击。
Improve the reliability and continuity of power supply system. Because multiple units are connected into a power grid, the voltage and frequency of power supply are stable and can withstand the impact of large load changes.

2、保养、维护更方便。多台机组并联使用,可以集中调度,分配有功负载和无功负载,能使保养、维修方便及时。
Maintenance and maintenance are more convenient. Multiple units can be used in parallel, which can be centrally scheduled, distribute active load and reactive load, and make maintenance and maintenance convenient and timely.

3、更具经济性。可以根据网上负载的大小,投入适当台数的小功率机组,以减少大功率机组小负载运行带来的燃油、机油浪费。
水果拉霸多人版More economic. According to the size of the load on the network, an appropriate number of low-power units can be invested to reduce the fuel and oil waste caused by the operation of high-power units under low-load.

4、未来扩展更具有弹性。只需安装现在所需功率之发电及并联设备,待以后公司需要扩展电网容量时,再增加发电机组,并且能方便地实现扩展机组的并机,令初步投资更显经济。
水果拉霸多人版Future expansion is more resilient. Now only need to install the required power of the power generation and parallel device, when the company needs to extend the grid capacity, after waiting for an additional generator set, and can conveniently realize extension set designer, the initial investment is more economic.

方案分类    Classification scheme

1、手动并机:采用灯光或同步表指示,该方法一般用于机械调速的老式柴油发电机组;
Manual parallel operation: the light or synchronous meter is used to indicate this method, which is generally used for the old diesel generator set with mechanical speed regulation.

2、半自动并机:自动并机,手动解列,一般用于工厂主用或备用电源;
Semi-automatic parallel machine: automatic parallel machine, manual disconnecting, generally used for the main use or standby power supply of the factory;

3、自动并机:市电停电,自动启动2台或多台发电机组,并机后向负荷供电,市电恢复,自动解列,机组自动停机,一般用于楼宇的备用电源;
Automatic weaver: mains power outages, two or more generators will start automatically after the weaver to load power supply, grid, automatic solution, the unit automatically stop, commonly used in the building of the standby power;

4、全自动并机:在自动并机柜的基础上,根据负荷的大小变化,并机柜完成多台机组的自动投入与并机,自动解列与停机的逻辑功能
Automatic parallel machine: on the basis of the automatic parallel machine cabinet, according to the change of load, and the cabinet completes the automatic input and parallel machine of multiple units, the automatic sequence and stop logic functions。
