Under the partial-automatic control mode, can the control button through man-machine interface accomplish startup, shutdown, combined floodgate, disjunction, synchronously, operation such as off-the-line.
Because the partial-automatic control mode is higher than automatic control mode priority, therefore, under automatic control mode, unit and circuit breaker controlled function thereof are still effective.
(4). automatic frequency load regulation
Under the partial-automatic control mode, power management system can be to carrying out frequency adjustment and load allocating at the net unit.Frequency-tuning range is rated frequency ± 0.25Hz, the active power adjustable range be rated power ± 5%.
(5). the power principle increases, subtracts machine
Under the automatic control mode, when the system power allowance is not enough (this value can be passed through the human-computer interaction interface setting), to possess entry condition, subsequent use unit that priority is the highest sends enabled instruction.If all units do not possess entry condition, the output failure alarm signal.
When the system power allowance is higher, to possess halt condition, priority minimum send halt instruction at the net unit.
When unit can't start, shutdown or circuit breaker can't close a floodgate, during disjunction, corresponding failure alarm signal output is arranged all.
(6). load shedding
When the electric current of the unit circuit breaker of flowing through surpassed certain limit, non-important load was laid down in power management system classification according to circumstances.
(7). heavy duty control
If receive heavily loaded request signal when power management system, will judge whether the margin of power of system is enough behind this heavy load starting.If margin of power is enough, the output heavy duty allows index signal prompting crewman heavy duty to close a floodgate; If margin of power is not enough, system can according to circumstances increase machine, till margin of power satisfies condition.
When not having subsequent use unit, the output failure alarm signal.
(8). fault is changed planes
When netting category-B faults such as the unit occurrence frequency is out-of-limit, voltage is out-of-limit, power management system will start subsequent use unit automatically and be incorporated into the power networks, then with the fault unit trip.
When not having subsequent use unit, the output failure alarm signal.
(9). the propeller power restriction
Power management system passes to propulsion control system with the system power allowance through 4 ~ 20mA current signal in real time.Propulsion control system can be formulated control law according to the margin of power situation, realizes advancing load (frequency converter) Power Limitation.Power management system provides subsequent use (redundancy) control signal under following two kinds of situation, the prompting propulsion control system realizes advancing load limitations.
When the system power allowance is low, power management system will increase machine automatically; In increasing the machine process, if the load sustainable growth, when margin of power was lower than a certain limit, the power output restricting signal was given propulsion control system, and the restriction of prompting propulsion control system advances load.This signal is as subsequent use (redundancy) control signal of propulsion control system.
When power management system detected the unit circuit breaker and trips for some reason suddenly, output was fallen power signal and is given propulsion control system, prevented the unit overload.This signal is as subsequent use (redundancy) control signal of propulsion control system.
