The invention discloses a method for controlling the active power of a hydroelectric unit in a double-suggested operating area, and belongs to the technical field of hydroelectric power generation control. Divide automatic power generation control function modules into power station-level AGC function modules, unit-level PLC function modules, and unit-level governor function modules and assign tasks; determine parameters, assignment relationships, and dependencies; pre-establish models for all units that are put into AGC control , to calculate the optimal operating range of the unit put into AGC control; and calculate the active power distribution value of the single-unit AGC, and carry out the active power control of the hydroelectric unit in the double-suggested operation area according to the obtained single-unit AGC active power distribution value. It is suitable for the hydropower station whose interval division is from low to high in the order of vibration area→recommended operation area 1→restricted operation area→recommended operation area 2 unit type, and can quickly calculate the stand-alone AGC of each unit according to the total active power setting value of the hydropower station Active power distribution value and stand-alone active power setting value can meet the operation requirements of the unit avoiding the vibration area and the restricted operation area at the same time.

The invention discloses a method for controlling the active power of a hydroelectric unit in a single recommended operation area, and belongs to the technical field of hydroelectric power generation control. Divide the automatic power generation control function into the power station-level AGC module, the unit-level PLC module and the unit-level governor module and then assign tasks, determine the parameters, assignment relationships and dependencies; establish all possible distribution modes and corresponding combinations that include AGC control units The intermediate table of the operation interval determines the optimal unit distribution mode of the units put into AGC control, and calculates the single-unit AGC active power distribution value, and performs the active power control of the hydroelectric unit in the single-recommended operation area. It is suitable for hydropower stations where the intervals are divided into vibration zone 1→restricted operation zone→vibration zone 2→recommended operation zone from low to high. It can quickly calculate the single-unit AGC active power of each unit according to the total active power setting value of the hydropower station. The distribution value and the active power setting value of a single unit can meet the operation requirements of the unit avoiding the vibration area and the restricted operation area at the same time.

The embodiment of the invention discloses a bandwidth adjustment method and device. The method comprises the steps of obtaining a bandwidth adjustment request; determining whether a request account number of the bandwidth adjustment request supports bandwidth adjustment; and if the request account number supports the bandwidth adjustment, adjusting a bandwidth of the request account number based on the bandwidth adjustment request. According to the method, a user can complete the bandwidth adjustment via an intelligent terminal, so that the low efficiency brought by adjusting the bandwidth at a place of business is avoided; and in addition, according to the method, before the bandwidth is adjusted, through a manner of determining whether the request account number of the bandwidth adjustment request supports the bandwidth adjustment, the condition that the adjustment is failed or the adjustment effect is not reached due to a fact that the request account number does not support the bandwidth adjustment during the bandwidth adjustment is avoided.
