Description
Technical field
The present invention relates to the photo-thermal power generation field, particularly for slot-type optical collector control system and the control method thereof in slot type photo-thermal power station.
Background technology
Solar light-heat power-generation technology (English name Concentrating Solar Power, be called for short CSP) utilize concentrator that solar radiation energy is reflexed on the heat collector, heat collector is the solar radiant energy energy transform into heat energy, and generates electricity by thermodynamic cycle process.As the important way of the extensive generating of solar energy, solar light-heat power-generation has a series of obvious advantages.At first, the carbon emission amount of its Life cycle is very low, according to foreign study 18g/kWh is only arranged.Secondly, this technology cost in existing solar energy generation technology is minimum, is easier to realize rapidly extensive industrialization.At last, solar light-heat power-generation also has very strong and compatibility advantage existing thermal power station and network system.
The solar light-heat power-generation technology mainly contains following four kinds: the generating of slot light collection heat, tower condensing thermal power generation, dish formula condensing thermal power generation and Fresnel condensing thermal power generation.
At present, in above-mentioned solar light-heat power-generation technology, the hot generation technology of slot light collection is the most ripe, is most widely used.The slot light collection heat generating system is by the paraboloid trough type condenser mirror sunshine to be converged on the focal line, at focal line tubular heat collector is installed, to absorb the solar radiant energy after focusing on.After fluid in the pipe was heated, the heat exchanger of flowing through heating water generates steam was generated electricity by means of Steam Power Circulation.This system adopts one dimension tracing mode to follow the tracks of sun continuous operation, follows the tracks of simple and easyly, and optical efficiency is higher, and the fluid operating temperature can reach 400 ℃, can satisfy the needs of generating.
Above-mentioned operation principle by the slot light collection heat generating system can be found out, the slot light collection heat generating system will obtain best electricity generation efficiency, slot-type optical collector in the system should constantly be in an only angle with the sun when work, because the position of the sun can change along with the time, so the control section in the slot light collection heat generating system should be controlled slot-type optical collector realization settled date tracking.According to controlled variable whether controlled quentity controlled variable is existed feedback, the settled date tracking mode of existing slot-type optical collector can be divided into closed loop, open loop and Open-closed-loop mixed-control mode.There are at present many researchs and patent to describe different tracking and controlling methods and system.For example, 1 United States Patent (USP) " US 2011/0168161A1, " Solar Trough Field System " " is mentioned a kind of control system that realizes the tracking of slot-type optical collector settled date with sun-sensor adjustment central authorities stepper motor as a reference.The solar radiation sensor that this settled date tracking control system utilization is installed on the slot-type optical collector catches the current position of the sun, then controls slot-type optical collector to aim at the current position of the sun.The defective of this system is that solar radiation sensor need to be installed on slot-type optical collector specially, solar radiation sensor is expensive, and need hundreds and thousands of slot-type optical collectors in the slot light collection heat generating system, therefore this type of control system cost is higher, is unfavorable for the popularization of slot light collection heat generating system.
The slot light collection heat generating system will obtain best electricity generation efficiency, except will doing the settled date tracking, also need to keep the thermal-collecting tube in the slot-type optical collector to be operated in ideal temperature, adjusting to the thermal-collecting tube operating temperature is also referred to as thermal technology's control, is used for realizing that the system of thermal technology's control is called as Thermal Control System.It is two processes that are closely connected that settled date follows the tracks of with thermal technology's control, in the process of settled date tracking, constantly need to do thermal technology's control operation, but in the prior art, the settled date follows the tracks of with thermal technology's control and is finished by settled date tracking control system and Thermal Control System respectively, and this two covers control system is separate, realized respectively by different software and hardwares, complex structure, with high costs, be unfavorable for the popularization of slot light collection heat generating system, and be difficult for each other cooperating, break down easily.

Step 102), after the control module (24) in the described slot-type optical collector controller (3) is received work order, the astronomical formula of storing according to described control module (24), geographic factor and the current time parameter of described slot-type optical collector (4) calculate described slot-type optical collector (4) and follow the tracks of the required angle on target that rotates to of the sun;
Step 103), described control module (24) obtains the current angle of described slot-type optical collector (4) from obliquity sensor (10), calculates direction and angular dimension that described slot-type optical collector (4) will rotate;
Step 104), described control module (24) drive motors (14), control the first hydraulic stem (11) and the second hydraulic stem (18), described slot-type optical collector (4) is rotated, until the current angle of described slot-type optical collector (4) equals angle on target in accuracy rating.
9. one kind in the described control method that realizes for the slot-type optical collector control system in slot type photo-thermal power station of one of claim 1-7, is used for realizing thermal technology's control, and the method comprises:
Step 201), the TEMP data T1 of slot-type optical collector controller (3) Real-time Collection slot light collection apparatus (4) and operating state data S1; Described operating state data S1 is used to indicate the duty whether slot light collection apparatus 4 is in the settled date tracking;
Step 202), according to step 201) the TEMP data T1 that obtains and operating state data S1 judge whether the slot light collection apparatus is in the duty that the settled date follows the tracks of, settled date is followed the tracks of duty and temperature is higher than given threshold value if the slot light collection apparatus is in, then be in abnormal operating state, carry out next step, otherwise, get back to step 201), continue monitor procedure;
Step 203), judge whether described slot-type optical collector controller (3) is in automatic treatment state, as be automatic treatment state, described slot-type optical collector controller (3) sends control command, drive the parts in the control slot type condenser arragement, so that the thermal-collecting tube in the slot light collection apparatus departs from focus point, send simultaneously warning and process information to described top control module (1); As be the manual handle state, then suspend the settled date of slot light collection apparatus and follow the tracks of, report to the police to described top control module (1), wait for that the attendant carries out manual maintenance.
