Detailed description of the invention
In conjunction with Fig. 2～3, the concrete enforcement of this patent is described further:
1 system starting process
Solar heat power generation system is had relatively high expectations to solar irradiance, thus before whole system startup, need good weather condition, if the condition of predicting the weather meets the demands, just can shift to an earlier date preparation system operation.The flow chart that system starts as shown in Figure 4.System operation prepares to mainly contain following steps, first the surge tank in Fig. 29 and the cold salt cellar 6 in Fig. 3 are injected to the fused salt of required separately respective amount, start electric heating system separately, by the detection to temperature sensor T3 and T6, make it reach melting temperature separately, continue heating, finally make it reach corresponding reliability service temperature, for example T3 reaches 150 DEG C, and T6 reaches 290 DEG C.Now, the tracing system of primer liner and concentrating collector, carries out preheating to pipeline, in order to avoid high-temperature molten salt brings pipeline thermal strain damage while flowing and fused salt heat dissipation capacity is excessive condenses.When every temperature index reaches requirement, open all system pipeline valves, prepare to start pump for liquid salts 1.The condition that pump for liquid salts 1 starts is that local solar irradiance reaches design objective, as irradiation level is greater than 300W/m
2or sun altitude is greater than 15 °.Met the demands when meteorological day; just can start pump for liquid salts 1; now need signal piping flow whether suitable; flow is too little easily causes that heat collector outlet temperature is too high, and the limiting temperature that exceedes system tolerance will cause device damage, if pipeline blockage is obstructed under extreme condition; may directly cause the damage of pump for liquid salts; at this moment, should there is corresponding counter-measure, as adjust flux or disorderly closedown maintenance.
By the Flow-rate adjustment to 1 pump, the outlet temperature of mirror field heat collector is met the demands, at this moment just can start the pump for liquid salts 2 in accumulation of heat loop, the same with thermal-arrest loop, mirror field, must the moment monitor pipeline mobility status, prevent the device damage that pipeline blockage causes.By the Flow-rate adjustment to pump for liquid salts 2, make the temperature of molten salt of hot salt cellar meet requirement of system design, as reach 450 DEG C～500 DEG C, under temperature meets the requirements of prerequisite, whether the fused salt liquid level that need to judge hot salt cellar reaches system safe operation requirement, and when liquid level is too low, No starting steam heat transfer path circulates loop.
Under the condition all meeting the demands in hot salt cellar 5 temperature, liquid level, open the bypass duct of steam heat transfer system, then start pump for liquid salts 3, first steam heat transfer part is circulated in bypass duct, guarantee in the normal situation of system flow, just can start when needed steam generator heat exchange path, close bypass, start Steam Turbine, operation generating.
The operation of pump for liquid salts 2 and 3 is independent, relevant again, independence depends on that control point is separately temperature and the load condition of each self-loop, and correlation is that the liquid level of cold and hot salt cellar is relevant, under the condition of limit liquid level, must ensure that pump for liquid salts 2 is identical with 3 flow velocity, just can maintain not interrupt run.For example, in the time that solar irradiance is higher, the flow velocity of 2 pumps will increase, if 3 flow rate pumps remain unchanged, the capacity in cold salt cellar is fewer and feweri, if in cold salt cellar liquid level drop to lower limit also for time, must increase 3 flow velocitys, or reduce by 2 flow velocitys.Take which kind of mode, depend on the type in power station.Certainly, under these conditions, if will reduce by 2 flow velocitys, also need to be coordinated by adjusting light and heat collection area, otherwise will bring system to heat up.
2 obnubilations in short-term, the abundant running of accumulation of heat
At the sun when cloud and mist blocks in short-term, solar irradiance sharply declines, if now system amount of stored heat is abundant, when the more or liquid level of fused salt meets the demands in instant heating salt cellar, answer conversion operation mode, reduce by 1 pump for liquid salts flow velocity, reducing thermal-arrest loop heat loss, guarantee that heat collector out temperature meets the requirements simultaneously, is mainly by the Flow-rate adjustment of 1 pump, the upper limit that heat collector outlet temperature is allowed lower than system, and heat collector inlet temperature is higher than the anti-freeze safe temperature of fuse salt.2,3 pump for liquid salts maintain normal operation.The normal operation that obnubilation recovers 1 pump in the past, concrete flow chart as shown in Figure 5.
3 obnubilations in short-term, the method for operation that accumulation of heat is not enough
This situation is comparatively extreme, while there is obnubilation, first 1 pump low cruise, but outlet temperature under the condition of low irradiance, still can not be ensured, simultaneously because amount of stored heat is inadequate, can cause hot salt cellar temperature to decline, in the time dropping to a certain critical value, should reduce the flow velocity of 2,3 pump for liquid salts, for ensureing system normal power generation, should start corresponding auxiliary heating system.If without auxiliary heating system, need halt system power generation part, heat transfer hold over system is answered primer liner companion's heat in case pipeline freezes.This method of operation is changed very uneconomical, switches complicated and utilizes the time short, so the system appearance that should avoid this situation in service should have enough amount of stored heat before i.e. system commencement of commercial operation, this class process reply flow chart as shown in Figure 6.
4 night the method for operation
The system method of operation at night and obnubilation in short-term, accumulation of heat is not enough, and the method for operation is similar, and when sun altitude is lower than 15 ° or arrive a certain moment, Jing Chang recovers initial position, no longer light and heat collection.Now, be to reduce the heat loss in light and heat collection loop, heat-transfer working medium is answered low cruise, and system with good conditionsi can empty to heat-transfer working medium continuous salt cellar as tower system.The design that power station is depended in the operation of accumulation of heat and steam generation heat transfer part and operation type, under the enough condition of amount of stored heat, maintain normal operating mode.Particular flow sheet as shown in Figure 7.
The 5 successive cloudy days methods of operation
The judgement of successive cloudy days is generally from on-the-spot weather forecast station, and under successive cloudy days gas condition, power station should start successive cloudy days fate line mode, generally should carry out on-site manual or Remote and switch.The successive cloudy days method of operation is differently that whether light and heat collection Jing Chang starts from the maximum of the method for operation at night, under successive cloudy days gas condition, does not need to start tracking lens field, other to night the method for operation similar.
6 other explanations
In system pipeline, there are relevant temperature, pressure, flow sensor and corresponding RACS to detect and automatically control for system mode, pipe valve switches for mode and is convenient to Maintenance and Repair, pressure limiting valve is used for limiting fused salt tank internal pressure, emptying for to pipeline of vavuum pump.
