Description
Technical field
The invention belongs to technical field of electric power, more particularly to a kind of power dispatching method.
Background technology
Generally, electrically or power transformer station is related to electrical transmission and distribution system, wherein, using transformator come by voltage from height
It is transformed into low or contrary.Electric power can flow through some transformer stations between power plant and electrical equipment or load, and can be with some
Step carrys out voltage of transformation.
Industrial equipment is related to strong energy consumption and including one or more special substations, and which includes the master for being connected to electric power
The upstream transformer station in source (electrical network or indoor electromotor) and for the different loads center point to the various parts for being distributed in industry
Both downstream transformer stations with electric power.In addition, industry can have the electricity generation system of its own to meet its energy requirement, and also
With electric power management system, for effectively processing electric power for its purpose.
Power management capabilities include getting rid of load, metering, measurement voltage, electric current, power, energy and other power qualities
Parameter, for effectively processing the electricity needs of various equipment and process, power fluctuation, facility constraints etc..Just becoming common
It is that the equipment of this species is found in the processing industry of such as refinery and electric power facility.But, this equipment is also suitable
In other processing industry, such as cement, paper pulp and papermaking, petrochemical factory, fertilizer, mining industry and metal, water and wastewater treatment factory
Deng.
Transformer station's (such as both upstream and downstreams mentioned herein above) generally comprises some power transformers and distribution becomes
Depressor, wiring, switch, reactive power and grounding apparatus.Need to protect these power equipments to avoid abnormal (such as electricity of power system
Stream and voltage surge) impact, and by providing different transforming plant protectings, control, monitor and function of measuring intelligence
Electronic installation (IED) is completing this target.IED is the equipment based on microprocessor, and which (for example, is broken with power system device
Road device, electromotor, transformator, electric lines of force, power cable, reactor, motor, capacitor bank etc.) it is associated.Generally, IED from
Sensor receives main electric power system information (as voltage and current) to perform various protections and function for monitoring.Common type
IED includes protectiveness relay system (protective relaying device), load tap switch (load tap
Changer) controller, chopper (circuit breaker) controller, reclosing (recloser) controller, pressure regulator etc..
Therefore, single IED can be performed in parallel some protections, metering, monitoring and control function.
The automation of transformation substations is formed for maintaining and controlling the distinct device being related in the various process in transformer station
Important and complicated aspect.Manually and automatically control command function is provided also, as closing and opening switchgear (chopper and cut-out
Switch (disconnector)) or lifting/drop-out voltage level to maintain desired voltage level.There are multiple agreements is used for
The automation of transformation substations, which includes many proprietary protocols with customization communication link.But, for automation device for transformer substation
For the sake of realizing the simplification with use, it is thus highly desirable to from the interoperability of the device of different providers.
From International Electrotechnical Commission (International Electrotechnical Commission, IEC)
IEC61850 standards advocate using common engineering model (for example, using the common engineering models of IEC61850 of logical node),
Data form and communication protocol realize interoperability between the intelligent electronic device (IED) from various manufacturers.In the recent period
IED so designed that support the IEC61850 standards for the automation of transformation substations, which provides interoperability and high level communication energy
Power, as GOOSE (towards the transformer substation case of general object) and MMS (manufacture message system) communications profile.
Power management capabilities (as getting rid of load) in processing industry (i.e. when electricity needs goes above supply of electric power,
Cut off the electric current in some line/loads) it is implemented as at present distributing in power automatic system and industrial electrical management system
Centralised functions.The centralized realization for getting rid of loading functional generally in the single process controller of upstream transformer station has some
Weakness.For example, it causes high capacity, and this is due to the integrated institute for complete power system network in single process controller
Loading functional is got rid of, wherein it is desired to dispose get rid of load.It will be appreciated by those skilled in the art that generally utilize getting rid of load for realizing electricity
Power balance in system.Under heavy duty, power balance is negative and usually requires that voltage support.Alternatively, gently bearing
Under the conditions of load, power balance is positive and needs inductive compensation.
Get rid of in load system currently available, the centralized loading process controller that gets rid of is communicated with each IED with from power transformation
The various feeder lines (feeder) at the place of station obtain needing input data (for example, the electricity for the LS (getting rid of load) based on power balance
Pressure, electric current etc.), (shed) command information (for example, for getting rid of the information of load) is got rid of to send to feeder line by corresponding IED.This
The feeder line that text is used is usually electric wiring, and which may include leading in electromotor, load, total line (busway run) or conduit
Body, bulk electric power is carried to sub- feeder line plate or branched line plate from service equipment or is divided into less circuit to block electric power by which
Certain point.(feeder line is typically also known as medium voltage line, and which is used to distribute electric power to electrical equipment or to less from transformer station
Transformer station).
Therefore, the availability of LS functions is solely dependent upon and centralized gets rid of loading process controller.It is centralized to get rid of loading process control
Any operation interrupted of device processed causes LS functions for whole transformer station is unavailable.
Power balance (and power balance principle) described herein is balanced from the supply of Generation Side and from processing
The demand of the load-side of the electric power in factory.Known to power balance calculating as being used herein below is related to electric network and component
Calculate to realize power balance.One skilled in the art will recognize that electric network be electric device (for example, resistor, inducer, electricity
Container, transmission line, voltage source, current source and switch) interconnection.
Therefore, need now a kind of power dispatching method badly, load dispatch can be improved based on the permission of electrical management principle
Function, it is ensured that the balance movement of electrical network.
