Group governor, #2 machine unit speed regulating device, #6 machine unit speed regulating device, #7 machine unit speed regulating device and #8 machine unit speed regulating device.
Wind power curve 202 is inputted into wide area governor 201, calculates the power instruction for needing to convey, the AGC of hydroelectric power plant
Server 207 (including old factory AGC205 and new factory AGC206) receives the power instruction and generates control instruction, and by the control
System instruction is sent to each Hydropower Unit LCU.Speed-regulating instruction is sent to accordingly by each Hydropower Unit LCU according to the control instruction
Each hydro turbine governor, realize to the power regulation of each Hydropower Unit, and obtain the regulating power of each Hydropower Unit.
The power regulation speed of Hydropower Unit has particularly important status in the present invention, how to determine Hydropower Unit function
Rate adjustment speed, for realizing that technical solution of the present invention has a major impact.Specifically, Fig. 3 is referred to, Fig. 3 is implementation of the present invention
Hydropower Unit power regulation speed schematic diagram in example, comprising:
Power shaft, time shaft, joint adjust target power, wind-powered electricity generation realtime power, water power target power, the real-time function of water power
Rate, Adaptive System of Water-Turbine Engine lag time, target power lag time and the time of relatively lagging behind.Local control unit LCU according to
The control instruction after speed-regulating instruction is sent to corresponding hydro turbine governor, realizes the power tune to Hydropower Unit
It further include the speed of determining power regulation before section；Correspondingly, the speed of the determining power regulation includes::
Wherein, VeIndicate Hydropower Unit power regulation speed, p90When indicating that Hydropower Unit power regulation amplitude reaches 90%
Hydropower Unit power, p10Indicate the power of Hydropower Unit when Hydropower Unit power regulation amplitude reaches 10%, t90It indicates
At the time of Hydropower Unit power regulation amplitude reaches 90%, t10At the time of indicating that Hydropower Unit power regulation amplitude reaches 10%.
It can be seen that the time that relatively lags behind includes:
The sum of target power lag time and Adaptive System of Water-Turbine Engine lag time.
Actual effect of the invention shows respectively by Fig. 4 and Fig. 5, by figure it can be seen that technical solution of the present invention
Validity in practice.Firstly, referring to fig. 4, Fig. 4 is in the embodiment of the present invention under Hydropower Unit measured power and wide area governor
Send out magnitude of power and error schematic diagram, comprising:
Measured power and wide area governor issue magnitude of power 401 and power error 402.The unit for participating in analysis includes #
1, #3, #7 and #8 Hydropower Unit.As can be seen that each Hydropower Unit measured power and the magnitude of power that wide area governor issues are basic
Identical, the error of the two only differs larger at individual moment, and most moment are all substantially close to zero.
Secondly, referring to Fig. 5, Fig. 5 is that the given power of each unit shows with the comparison of measured power numerical value in the embodiment of the present invention
It is intended to, comprising:
#1 power of the assembling unit given value and measured power value 501, #3 power of the assembling unit given value and measured power value 502, #8 machine
Group power given value and measured power value 503 and #7 power of the assembling unit given value and measured power value 504.Wherein, it is made of curve
Be each Hydropower Unit measured power value, by rectilinear(-al) be each Hydropower Unit power given value.It can be seen that each
The measured power value and given performance number of unit have larger difference.The adjusting situation of each Hydropower Unit refers to table 1, from table 1
Be observed that two o'clock, 1) within five periods, #8 power of the assembling unit movement lag time is generally greater than #1#3#7 unit, this with
Monitoring system connects to the communication time of local LCU, the communication time of LCU to governor, speed-regulating system original machine power to guide vane
The lag time of power device stroke is related, due to lacking coherent signal, can not judge the main reason for leading to power movement lag；2)
General power lag time is bigger than the maximum lag time of each unit.
Period of 1 power deviation of table greater than 50MW counts
By table 1, available Hydropower Unit power deviation is greater than the period of 50MW, and the period and Hydropower Unit is inclined
Period of the difference less than or equal to 50MW is compared, and determines the regulating power of Hydropower Unit.If the ratio that the former accounts for the latter is less than
25%, then it is assumed that the regulating power of Hydropower Unit can satisfy demand.It is inclined to there is power in five periods as can be seen from Table 1
Difference is greater than 50MW, maximum power deviation -118.5MW, and the duration reaches 14 seconds.Active power actual measurement to this five periods
Value is counted respectively relative to active power given value lag time, power regulation speed, and see Table 2 for details, table 3.
2 typical time period power lag time of table
3 typical time period power regulation speed of table
Wherein, it is calculated when the power regulation speed in table 3 calculates using 90% power regulation amplitude.It, can be with by table 2
Obtain typical time period (11:14:12 to 12:13:31) Hydropower Unit power lag time.The case where not considering power lag
Under, the power regulation speed of each unit is shown in Table 2.Table 2 shows that 1) #7#8 unit adjustment speed is with respect to #1#3 unit adjustment speed
Faster, indirect reaction goes out power regulation mode tuning speed faster；2) #8 unit adjustment speed faster compared with #7 unit, #1 unit tune
It is fast to save speed ratio #3 unit adjustment speed.
1~table of consolidated statement 3, it can be seen that the relatively high power deviation in each period is mainly stagnant by Hydropower Unit performance number
Afterwards caused by Hydropower Unit power given value, for example, power deviation is more than -100MW in second period and the time maintains 14
Second is mainly caused by the power lag of #8 unit, therefore, ensures electricity net safety stable again simultaneously improving wind electricity digestion capability
Operation aspect, the time-lag effect of Hydropower Unit single-machine capacity are more even more important than water power single machine adjustment speed.
