Description
Technical field
The present invention relates to a kind of emulation mode of Steam Turbine transient Model.
Background technology
Power system be one by generating electricity, transmitting electricity, power transformation, the equipment such as distribution and electricity consumption, and auxiliary control appliance and guarantor
The ultra-large complication system that protecting system is formed, element are numerous.The function of power system is by the primary energy of nature
Electric energy is changed into by generation power device, then each user is supplied power to through transmission of electricity, power transformation and distribution.Power quality index
Mainly there are frequency, voltage etc., wherein frequency is both to characterize the leading indicator of the quality of power supply, is the important parameter of system operation again,
Therefore frequency is maintained to be had great significance near planned value for power system stability operation.And keep the frequency at plan
Premise near value is the balance of power system active power.
Power system active power balance is an extremely complex process, and it is numerous that its equilibrium process is related to factor, has
The characteristics of Multiple Time Scales, more means.In order to effectively complete the active power balance of interconnected network, it is necessary to which more deep grinds
Study carefully；Simultaneously because electric power is the lifeblood of national economy, the safe and stable operation of power system is for industrial production and people's lives
Important in inhibiting, therefore, about active balance in terms of achievement in research can not possibly directly apply in experimental stage it is actual
Power system, otherwise once accident occurs, production pause, life confusion will be caused, even jeopardize the person and equipment safety, formed
Extremely serious consequence, so give loss caused by national economy can be considerably beyond the loss of power system in itself.
In order to avoid unnecessary loss mentioned above, in practical operation by the correlation test in analogue system come
Checking research scheme is respectively provided with correctness and reliability under the service condition for being possible to face；Therefore, using accurate easy-to-use
The correlative study for power system active power balance of emulation platform and mode it is particularly significant.Emulation of the prior art is flat
Platform and emulation mode mainly have following several：1. based on the emulation of equipment transient Model, this emulation mode dynamic process is portrayed
It is fine accurate, model parameter is complicated, simulation time is longer, is the middle length towards minute and hour magnitude due to active balance emulation
The system operation dynamic simulation of time scale, the dynamic process of second level yardstick is not concerned with, and higher is required to simulation efficiency；2. pin
To the static Simulation of a wide range of power network, the Load flow calculation of such as power network, this emulation mode ignores all middle dynamic mistakes completely
Journey, last steady result can only be provided；3. the emulation based on algebraic operation and abstract model, such as document Yu Ba and Wei-
Dong Li.A Simulation Scheme for AGC Relevant Studies.IEEE Transactions on
Power Systems,2013,28(4):The emulation mode that 3621-3628. is proposed, its core is using law of conservation of energy as base
Plinth, and unit model is abstracted as end features parameter, have the advantages that model parameter is simple, simulation efficiency is high, more suitable for
Multizone long-time simulation study needed for active balance, but because this mode is special using simple and unified end output
Property parameter describing mode, it is impossible to distinguish the performance difference between all kinds of units, cause long term dynamics simulation process error excessive, no
The simulation accuracy demand of active power balance research can be met well.
In summary, the 1. kind emulation mode model excessively finely cause simulation time long, it is difficult to it is practical；And wattful power
The dynamic process of whole system in minute~hours yardstick is focused in rate balance emulation, not high to dynamic detail；Simultaneously
The 1. kind emulation mode be largely modeled using the differential equation, and be often based upon iterative method for differential equation, it is necessary to
A large amount of to calculate, simulation efficiency is than relatively low, especially when active balance research is frequently necessary to (such as the moon, year) emulation for a long time, meeting
Cause emulation time-consuming long；The 2. kind emulation mode be to be emulated for a wide range of Power System Steady-state, only retain steady result, have no dynamic
State process, and the simulation study of active balance correlation to all kinds of generating sets in system, it is necessary to simulate, and be directed to the load second extremely
The fluctuation of minute level and be adjusted, therefore the 2. kind emulation mode be not particularly suited for active balance emulation；3. the plants emulation side
Although formula simplifies model and improves simulation efficiency, but have ignored all kinds of unit performance differences using unified model, active
Certain error can be caused in the time scale of emulation by balancing, and cause emulation dynamic process precision inadequate, and active balance emulation is logical
Often need the property difference for reflecting different type unit such as Steam Turbine, water turbine set etc.；It is if guarantee simulation accuracy, then necessary
Using transient Model, simulation efficiency certainly will be caused low, it is difficult to practical；According to simple abstract model, although simulation efficiency
Ensured, but can cause emulate dynamic process it is not accurate enough, simulation result can not play actual directive function.
