6 FAQs about [Hong Kong loadshedding power backup]

What is the largest emergency backup power supply system in Hong Kong?

How does load shedding affect a power system?

... As a result, grid operators are forced to resort to load shedding to sustain the system at its current level . Load shedding is a power system control procedure intended to reduce or limit a specific amount of electrical load when the demand for electricity surpasses the supply capacity of the network .

Why did HK Electric shut down L7 & L10?

In the course of the shutdown of L7 and L10, the power output of these two units decreased rapidly and the total power generation of HK Electric was insufficient to meet the load demand. It in turn led to a rapid drop in system frequency.

What happens if load shedding occurs at bus 7?

or bus 9 is settled bellow the case of load shedding at bus 7. power mismatch. The frequency drop events are triggered electrical power increasing (load increasing). disturbance, the voltage reducti on will be experienced. Thus system attempt to restore the power system voltages. injection ( P). This behavior causes that the value of scheme.

When was the last power interruption incident in HK Electric system?

It was a very rare incident in HK Electric’s system, the last power interruption incident of similar scale occurred in the year 1994 which was caused by an incident outside HK Electric system. Electricity supply to about 44,000 customers scattered in HK Electric’s supply areas was interrupted in this incident.

Why does Hong Kong International Airport need a backup system?

To ensure stable round-the-clock airport operations, Hong Kong International Airport (HKIA) requires reliable electricity supply and installs backup system for emergency purpose.
