Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention. The reference numbers in the present application are only used for distinguishing the steps in the scheme and are not used for limiting the execution sequence of the steps, and the specific execution sequence is described in the specification.
In practical application, Automatic Generation Control (AGC) can be used to perform secondary adjustment on the output of the grid unit to meet the control target requirement. Basic goals of Automatic Generation Control (AGC) in normal operating conditions of a power system may include at least one of:
1) the load change of the power system is automatically tracked by power generation;
2) maintaining the power system frequency at a predetermined value (e.g., 50Hz) in response to random variations in load and power generation;
3) distributing system power generation power among all regions, and maintaining net exchange power among the regions as a planned value;
4) adjusting the power generation power according to the power generation plan for the periodical load change, and realizing online economic load distribution for the load deviating from the forecast;
5) and monitoring and adjusting the spare capacity to meet the safety requirement of the power system.
The circulating fluidized bed unit comprises a circulating fluidized bed boiler which adopts clean coal combustion technology with the highest industrialization degree. The circulating fluidized bed boiler adopts fluidized combustion, and the main structure of the circulating fluidized bed boiler can comprise a combustion chamber (comprising a dense-phase zone and a dilute-phase zone) and a circulating return furnace (comprising a high-temperature gas-solid separator and a return system). The biggest difference with the bubbling fluidized bed combustion technology is that the operation wind speed is high, heterogeneous reaction processes such as combustion and desulfurization are strengthened, the boiler capacity can be enlarged to a large capacity (600MW or above grade) acceptable by the power industry, and the circulating fluidized bed boiler well solves the basic problems of thermology, mechanics, materials and the like and the engineering problems of expansion, abrasion, over temperature and the like, and becomes an advanced technology for energy utilization of difficult-to-burn solid fuels (such as coal gangue, oil shale, municipal refuse, sludge and other wastes).
The circulating fluidized bed unit may further include a steam engine part interlocked with the circulating fluidized bed boiler, and the steam engine may be operated in cooperation with the above-described machine tool. Load and coal type variations are the dominant external disturbances in the circulating fluidized bed unit controlled combustion process. Generally speaking, the regulation control system needs to stabilize the main steam pressure, the main steam temperature, the bed temperature, the oxygen content, the hearth negative pressure and the bed pressure in a proper range under external disturbance, maintain proper air-coal ratio, primary air ratio, secondary air ratio, hearth negative pressure, ash concentration and hearth outlet temperature, and realize energy balance, material balance and momentum balance (mass balance), thereby ensuring safe and economic operation of the boiler.
Because the material flows, burns and exchanges heat in the hearth of the circulating fluidized bed boiler. The control characteristic in a circulating fluidized bed boiler is thus a large hysteresis, strongly coupled, time-varying nonlinear system.
Wherein the strong coupling is represented by: one adjusted parameter is simultaneously influenced by the common influence of several adjusting parameters, for example, the bed layer temperature is controlled by a plurality of parameters such as coal feeding quantity, limestone supply quantity, primary air quantity, material returning quantity, slag discharging quantity and the like. Meanwhile, one adjusting parameter influences a plurality of adjusted parameters, such as coal feeding quantity, main steam pressure, bed temperature, hearth temperature, excess air system, SO2 content and other parameters.
Wherein, the main reaction of large hysteresis is in the combustion and heat exchange process: the contact combustion of the fuel and the air of the circulating fluidized bed unit until the fuel is burnt out takes a long time, and simultaneously, the related factors and links are more in the heat exchange process, the capacity of the links is large, and the heat exchange is greatly delayed.
Wherein the time-varying nonlinearity is represented by: when the circulating fluidized bed unit is used for burning different coal types and under different loads, the combustion and heat exchange processes in the furnace are greatly different, and the corresponding primary air quantity distribution, secondary air quantity distribution, air coal distribution and ash concentration are also different. For example, the primary air rate is lower when anthracite coal with low volatile matter is used, and the primary air rate is higher when bituminous coal with high volatile matter is used. Similarly, the proportion of the primary air and the secondary air of the same coal type under different loads can be different.
In the practical application process of the circulating fluidized bed unit, the control structure of the traditional pulverized coal boiler is directly used for automatic power generation control of part of the circulating fluidized bed unit, namely, the coal feeding amount of the boiler and the opening of a main steam valve of a steam turbine are used as input quantities, and the power of the unit and the pressure of the main steam are used as output quantities. The characteristic of the circulating fluidized bed boiler is different from that of the traditional pulverized coal boiler, so that the deviation of the main control pressure of the steam turbine is large, and the load of the unit is poor in adjustment precision and slow in load change due to the pressure deviation in the process of severe load change of the unit power. When the high-load operation is carried out, the main steam pressure has large fluctuation, so that the protection action is caused, and the load of the unit is difficult to track the target load instruction in a high-load interval. In the process of frequent load change, the coal feeding adjustment changes quickly, so that the fluctuation of the coal quantity is large, and further, the fluctuation of the pressure and the air quantity adjustment is large, so that the control effect of the oxygen quantity at an outlet is poor.
Therefore, how to automatically control the power generation of the circulating fluidized bed unit is an urgent technical problem to be solved.
