Abstract
The invention discloses an integrated self-adaptive coordinated control system for magnetic suspension ORC waste heat power generation. According to the integrated self-adaptive coordinated control system, the original chemical engineering production line and waste heat power generation line are connected to the same database, the same industrial Ethernet, the same DCS/PLC software, the same software-compatible DCS/PLC hardware and the same human-computer interface to realize integrated self-adaptive coordinated control, so as to guarantee the safe, long-term and stable running of equipment, thus the waste heat of a factory is maximally converted to electric energy, and the enterprise benefits achieve maximization.
Description
Technical field
The present invention relates to field of industrial automatic control, specially refer to a kind of magnetic levitation ORC waste-heat power generation integrated self-adaptive coordinated control system.
Background technology
Organic Rankine circulation (Organic Rankine Cycle is called for short ORC) is to take the Rankine cycle that low-boiling-point organic compound is working medium; Low-grade industrial waste heat resources characteristic: there is diversity (gaseous state, liquid state, complicated component), low parameter (temperature is lower than 200 ℃), unstable (pressure, flow rate fluctuation amplitude is large, frequency is fast), such as a large amount of high-temp liquids of factory's gas shaft, torch, papermaking and pulp industry, the production low temperature waste gas of the tail gas of the exhaust of gas turbine and diesel motor, chemical metallurgy industry etc.
Present status in China, for waste heat recovery, utilize the exploitation of GENERATION MARKET, in view of effects limit such as technique, equipment, technology, investment repayment height, substantially be all for high-grade used heat (main temperature is higher than 250 ℃) field at present, utilize single pressure, two pressure, flash evaporation power generation technique, utilize the generating of water vapour pushing turbine, in view of high-grade waste heat recovery power generation project technology comparative maturity, investment repayment higher, all extremely fierce in this field competition; But in low-grade exhaust heat field, have that temperature is high lower than 200 ℃ and vary within wide limits, change frequency, complicated component, the feature such as little and loose, limitation due to technology, only have at home few to relate to, be all the organic Lang Ken circulation electrification technique as well as utilizing, this technique is to utilize the organic working medium of vaporization to promote the generating of magnetic suspension turbine machine.
Domestication factory is due to problems such as production planning, fund, technology; former plant produced line and magnetic levitation ORC waste-heat power generation system are not mostly to build simultaneously; even build the same period; because former plant produced line and power house belong to different industries, desired Automation Specialty technology is different; the control system adopting neither same brand; even the system of same brand, is also two systems completely independently, therefore conventionally can form two completely independently islanded systems.Because two systems are completely independent, do things in his own way, often in actual production process, data are not shared, are linked up not in time, can cause thermal source waste, even may have influence on the normal production of original production line.
Summary of the invention
For addressing the above problem, the invention provides a kind of magnetic levitation ORC waste-heat power generation integrated self-adaptive coordinated control system, native system provides a kind of same database based on whole factory, same Industrial Ethernet, same DCS/PLC software, same softwarecompatible DCS/PLC hardware, the integral control system of same man-machine interface, be the different control stations of the same system of former chemical production line and waste-heat power generation system seat, by overall data library inquiry data, failure judgement, problem analysis, by an Industrial Ethernet, realize exchanges data, control interlocking, blind spot shows, by same man-machine interface, realize coordinated operation, guarantee the realization of process strategies and production management, guarantee device security, for a long time, steady running, reaching waste-heat power generation utilization maximizes.
Technical solution of the present invention:
From design, former chemical production line DCS, waste-heat power generation DCS are carried out to synchronous integrated design, adopt the control theory in " territory ", be chemical production line, waste-heat power generation workshop section as whole DCS in factory different " territory " systematically, by sharing same operating platform, same Industrial Ethernet, same database, same compatible brand system hardware, realize data sharing, resource sharing, coordination control, chain operation, thereby realize partial operation, global monitoring, the object of stabilised quality, raising generating.
From enforcement, can be synchronous, also can implement a certain " territory " step by step, thereby realize whole standardized integral control system.Former chemical production line " territory " is comprised of production line control station; Waste-heat power generation " territory " is comprised of used heat heat exchange control station, magnetic suspension turbine control station, generator control station.
Field layer: site intelligent bus apparatus adopts Profibus DP communication standard and cpu controller to communicate;
Control and management layer: adopt Industrial Ethernet ICP/IP protocol to realize the communication between system controller and active station; Separately between each layer connect each other again, by computer network system, connect, to reach the decentralised control of DCS, the object of centralized management.
By production line control station, used heat heat exchange control station, magnetic suspension turbine control station, generator control station access enterprise backbone network, it is Industrial Ethernet.Adopt Industrial Ethernet ICP/IP protocol to realize the communication of enterprise's backbone network, backbone network can be star topology, ring topology, can be also bus type topological structure.
It is engineer station that former chemical production line " territory " and waste-heat power generation " territory " share a station server, production line control station, used heat heat exchange control station, magnetic suspension turbine control station, Generation Control station are sent to server by Industrial Ethernet by signal data, signal data is delivered to each active station after server process, by operator, production line is monitored to control.Owing to having shared same station server, each workstation is connected directly to Industrial Ethernet, by server, directly read whole signals, data message, in operator station, realize exchanges data, control interlocking, blind spot demonstration.Realized the completely shared of data message, former chemical production line operative employee also can monitor other workshop sections and the waste-heat power generation station operational factor of this line in this workshop section of operation, and waste-heat power generation operative employee is also like this.Former like this chemical production line workshop section and waste-heat power generation workshop section are no longer separate, do things in his own way.In order better to guarantee clear definiton of powers, the operative employee who sets our station in system only has operation and monitors authority our station, and its station is had to supervision authority, there is no operating right.
The invention has the beneficial effects as follows, by native system realize exchanges data, control interlocking, blind spot shows, original production line and the seamless link of waste-heat power generation station track, integrated self-adaptive coordination control have been guaranteed, guarantee device security, long-term, steady running, factory's used heat is maximized and be converted to electric energy, make the performance of enterprises reach maximization.
