Description
Technical field
It is in particular to a kind of to be based on zonal wind-powered electricity generation the present invention relates to a kind of power generation energy resource centralized monitoring system
Based on various power generation energy resource centralized monitoring systems.
Background technology
Development and utilization regenerative resource, such as wind-force, solar energy and water energy, are to solve energy crisis and environment dirt
The effective way of dye problem, but need to evade the influence that its randomness brings power network, how to optimize the various energy,
Realize effective supplement, to wind-powered electricity generation, the jointly controlling of water power, dispatching, this is accomplished by how research enters for enhancing
Row regionality thermoelectricity, wind-powered electricity generation, the reasonable resource of water power equal energy source form allocate and by region the energy it is effective
Complementary and joint, for dispatching of power netwoks provides exerting oneself for stabilization, and then stabilizes the discontinuous, unstable of wind power output
To the difficulty that electric power system dispatching is brought, the utilization ratio of the clean energy resourcies such as wind energy, water energy is improved, reduce power supply
Cost.Instantly, support is provided to providing regional comprehensive energy services in the urgent need to technological means.Current
Wind farm monitoring system is directly connected by AGC substations with dispatching of power netwoks end AGC main websites, is received power network and is adjusted
The generation schedule that degree main website is issued.Under normal circumstances, consider that dispatching of power netwoks is paid the utmost attention to can based on power grid security
By property thermoelectricity high, and water power typically just participates in Load Regulation, and wind-powered electricity generation is even more marginalisation, largely abandons wind, greatly
The big utilization rate for reducing clean energy resource.
Currently, in the various energy resources system of regional center scheduling, thermoelectricity, the control technology relative maturity of water power,
Thermal power output stabilization, system maturation；Power station has realized the integrated of the interior system in station substantially, and power station is received
The management that National Flood Control is done, flood season (April-September) needs timely responding to for Field Force, and personnel can drop back model
Enclose less；And the problem of wind power plant is more protruded, on the one hand scene covers systems and deposits, and producer's communication protocol is not
Unified, another aspect wind power plant is mostly remote, and bad environments, Field Force's Working Life is very inconvenient；
So wind power plant realizes the system integration, number in station in the urgent need to setting up a set of region remote control terminal system
According to unification, and realize that site administrator drops back by remote monitoring mode；Especially wind-powered electricity generation is intermittent, random
Property feature also turn into impact grid stability factor.How to be made overall plans and coordinate in region, realization has to blower fan
Effect control, for the fluctuation for reducing overall output power, the economic benefit that raising whole region is powered is most important.
Can be divided into substantially in region according to monitored object regionality wind-powered electricity generation region remote control terminal system
The monitoring of the heart, the monitoring for wind power plant and three parts for blower fan, District integrated control center have former wind power plant with
The AGC functions of dispatching of power netwoks, while again include the partial function of dispatching of power netwoks, so as to possess integrated dispatch
Premium Features.The function of acceptable constantly reinforced region centralized control center, and aid decision is carried out by data analysis.
Therefore, the key for setting up District integrated control center is to realize the remote monitoring of wind power plant, by setting up standard
Communications protocol, realizes the centralized watch to wind power plant different type unit information and being uniformly controlled across producer；It is logical
Cross network analysis and integrate the related global data of blower fan, realize the control to different manufacturers separate unit power of fan；Close
The various energy in reason dispatcher-controlled territory, realize that the energy is complementary, thoroughly eliminate adverse effect of the wind-powered electricity generation to power network；Pass through
Remote monitoring mode, realizes the recession of site administrator.
At present, the controller of fan of matched with blower more by well-known manufacturer (German Beckoff, Austrian Ingeborg Bachmann,
Japanese Henghe, Denmark's rice tower etc.) provide, the supporting SCADA system of wind power plant is generally supporting blower fan manufacturing firm
There is provided, system is the secondary development based on SCADA system mostly, and it is logical that blower fan producer SCADA system is externally provided
News agreement disunity, the mainly Protocol of OPC, Modbus or producer.Due to various wind in wind power plant
The sensor and executive component of group of motors come from different vendor, and connected mode and communication protocol are not quite similar, by stages
The wind power plant of construction exists and has a case that Duo Tao blower fans producer SCADA system in a wind power plant, producer's communication
The disunity of agreement and interface, it is difficult to realize that data are managed concentratedly, brought to live operation maintenance and personal management
Difficult the problems such as.Normal operation for wind power plant is extremely inconvenient, simultaneously because communication protocol and interface are asked
Topic, causes wind power plant to monitor and there is no method to realize being interacted with dispatching of power netwoks department, including data upload and regulate and control to refer to
The reception of order.Additionally, each blower fan producer SCADA system generally only has wind power plant operation data information at present
Collection and simple management function, the senior application function for not possessing assisting wind generating normal operation.
The content of the invention
