Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as the foundation of the utility model being done any restriction.
Embodiment.The utility model is the improvement to existing fuel-burning power plant level of factory load distribution system, and what present domestic fuel-burning power plant load distribution adopted is that automatic electricity generation control system is directly transferred mode, as shown in Figure 2.Power network schedule automation energy management system EMS in the automatic electricity generation control system directly assigns the load instruction to each unit scattered control system DCS according to client's workload demand by remote terminal unit RTU.Present this laod sharing mode power network schedule automation energy management system in many cases EMS can't learn the equipment operation condition of particular rack, when genset is in an emergency, can cause the fortuitous event of some crisis safe operations.In addition, present this laod sharing mode also can't be realized the Optimization Dispatching of loading between each unit of full factory.
Fuel-burning power plant of the present utility model level of factory load distribution system as shown in Figure 1, it is to set up a load optimized distribution device LDS between existing power network schedule automation energy management system EMS and unit scattered control system DCS; The scheduling signals of power network schedule automation energy management system EMS is connected with load optimized distribution device LDS through remote terminal unit RTU.Control signal and the needed unit data of load optimized distribution device LDS that load optimized distribution device LDS sends are carried out exchanges data by unit scattered control system DCS, and load optimized distribution device LDS is according to the instruction of power network schedule automation energy management system EMS and the automatic configuration optimization load distribution of the load-bearing capacity scheme of each unit; When satisfying the load responding rapidity requirement, realize load optimum load distribution effects.The dispatch command of power network schedule automation energy management system EMS can be selected 96 point load curves or Real-Time Scheduling instruction.
The load distribution system comprises controller, controller 4 is computing machines that level of factory load distribution system of power plant is installed, level of factory load distribution system of power plant can generate a kind of load based on rapidity and economy multiple-objection optimization automatically and optimize Dynamic Assignment, this schemes synthesis is considered the economical and quick tracking performance of full factory, under specified response speed (or response time) full factory total load is distributed by the minimum mode of total consumption of coal.In order to guarantee the non-stop run of load distribution system, controller is made of master controller 3 and preparation controller 4, and when master controller 3 was out of service, preparation controller 4 was taken over the work of console controller 3 at once.Controller receives the full factory load instruction that power network schedule automation energy management system EMS sends in real time, also receives each unit real-time running data that the diffusing control system DCS of slave component collects simultaneously.Load Optimal Distributing System LDS comprises performance server 6, and performance server is that the computing machine that unit performance calculates is installed, and unit performance calculating is adopted two kinds of algorithms of positive and negative balance that each load point of each unit is carried out performance computation and revised mutually.Preserve the performance data of each unit in the performance server 6, performance server 6 is calculated its coal consumption value, for its coal consumption family curve of active and standby controller match automatically by the real time data that each unit scattered control system DCS gathers a plurality of load point.Described load Optimal Distributing System LDS comprises the long station 5 of value, can realize functions such as optimization pattern under the selection, affirmations of coal consumption curve, manual command setting, input 96 point load curves, selection automated manner of the load instruction of full factory and each unit load instruction hand automated manner or ratio mode by being worth long station 5 runtime value length.
A kind of fuel-burning power plant level of factory load optimized distribution device, as shown in Figure 1.This system comprises the power network schedule automation energy management system EMS and the remote measuring and controlling system RTU of two-way connection successively, and unit scattered control system DCS; Between remote monitor device RTU and unit scattered control system DCS, be provided with the LDS of load distribution system, load Optimal Distributing System LDS respectively with remote terminal unit RTU and two-way connection of unit scattered control system DCS.Load Optimal Distributing System LDS comprises input/output interface 1, and input/output interface 1 is grown station 5 and 6 two-way connections of performance server with master controller 3, preparation controller 4 values respectively through switch 2.Switch 2 is terminals of various command signals, control signal and the data-signal hardwire mode that collects.Master controller 3 is connected with RTU is two-way respectively with preparation controller 4, and communication modes adopts the redundant means of 1801 stipulations as the hardwire mode.For the demanding signal of real-time, all adopt both redundant each other means to connect, to guarantee the reliability of data,, can not adopt redundant fashion for the less demanding signal of real-time.The different demanding number of signals of its real-time of unit quantity is also different, and 4 units probably have 150 key signals; The signal that real-time is not high probably has 1000.Performance server 6 and two-way connection of unit scattered control system DCS, connected mode adopt the redundant each other mode of hardwire and OPC communication.To guarantee data reliability.
