The scheme that the utility model patent is advocated is, distributed water power, wind-powered electricity generation, solar energy, and other are all by mesh Preceding power network is defined as the electric energy of " rubbish electricity ", constitutes a direct current transmission and distribution net, not high to some power qualities and parameter request Customer power supply, such as ordinary people's household electricity turns into two electricity for being completely independent operation with the bulk power grid being originally defined Net.Former bulk power grid can receive thermoelectricity, medium water power, nuclear power above etc., and capacity is big, quality is high, parameter stability power supply point It is that those require that power quality is high, parameter stability as exchange transmission and distribution network, and load terminal user bigger than normal powers, such as Industrial production processing factory, scientific research institutions etc..

The utility model can power with AC network (national grid) party-line transmitting to terminal user.

Distributed power source is only incorporated into the power networks and the bigger advantage of competence exertion and obtains bigger development.To distributed power source For power network, it is incorporated into the power networks and can both be realized by with existing AC distribution net party-line transmitting, it is also possible to light-duty by setting up The electricity that distributed power source sends is directly sent to circuit the form of electricity consumption side.The former can save substantial amounts of transmission line construction into This, and the latter needs to set up new circuit, takes new line corridor.Both modes that are incorporated into the power networks are to promoting new distribution type The fast development of power supply will play a great role, and being incorporated into the power networks for distributed power source power network, is the existing mode that is incorporated into the power networks Reasonable supplement, is to realize that the hardware surfed the Net at a competitive price in pure meaning ensures, will also advance the quick of new distribution type power supply Development.

The basic thought of transmission of electricity that alternating current-direct current is collinear is：Pass through certain device on conventional AC transmission line of electricity by direct current work( Rate is modulated into transmission voltage and is fed in transmission line of alternation current, allowed in the case where power transmission line electrical characteristic is met exchange and Direct current is transmitted in same power transmission line；And the opposite side in circuit is again demodulated direct current by certain device from power transmission line Come and supply customer loads after inversion or step-down.Because three-phase conducting wire is superimposed DC component simultaneously, therefore the top-stitching of wire is electric Pressure will not be raised, and span between existing line is not changed, and simply wire voltage-to-ground increased a DC component.No matter from technology In upper or practical application, transmission problem can be solved with perfection, in this way, power grid construction cost can be saved significantly, prevented A large amount of construction costs are imputed to ultimate consumer.For China's energy revolution, Renewable Energy Development increases renewable energy Source share is opera involving much singing and action.And hereafter, the history of the power network that can terminate " abandon wind and abandon light " is fully dissolved distributed " rubbish electricity " It is possibly realized, hinders the bottleneck of power industry development to be resolved, the resource of distributed power source is no longer wasted, distributed power source Cost of electricity-generating will be greatly lowered, terminal client will be greatly benefited.

Preferably, described direct current transmission and distribution Netcom is delivered to step-down power transformation after crossing primary substation boosting through transmission line of electricity Stand, terminal user is delivered to after being depressured through step-down substation.

Each the element vector quantization in distributed power source power network whole system, and as an independent control unit, It is based on internet big data computing, completely disengaging from manual intervention, fully rely on automatic dispatching, can dissolve form of ownership " rubbish electricity " network system.Distributed power source power network is that load and electric energy distributed power source and its institute's energy supply turn The device such as change, protect, monitoring as a system, forming a complete power network for intelligence completely, in a distributed manner water turbine power station Based on generator unit, including internal combustion engine, the electricity generation system such as miniature gas turbine, fuel cell, solar energy, wind energy includes it In, make it possible to dissolve photovoltaic, wind-powered electricity generation these regenerative resources.Can not only isolated operation, and other power networks can be incorporated to. And it is achieved that distribution can be worked as by external power grid supplement vacancy when power supply function is not enough in distributed power source power network Unnecessary electricity can be conveyed to external power grid when power supply generated energy is big in power generating facilities and power grids.Concrete structure diagram is as shown in Figure 1.

The power system of distributed power source power network is by power plant, primary substation, transmission line of electricity, step-down substation and user Composition.The exit potential of TRT is from 3.15KV to 26KV.And different power plant's exit potentials is typically all unequal. This voltage class can not be supplied directly to user, so to be all first sent to primary substation, carry out collecting and distribution for electric energy. The electric energy sent out from primary substation is different according to supply object, transmission range difference can be divided into 10kV, 35kV, 66kV, The various voltage class such as 110kV, 220kV, 330kV, 500kV.In general, transmission range is more remote, voltage class is higher (defeated Under conditions of electrical distance and transmission line capability are certain, from voltage class higher, the power loss on circuit can be reduced).380/ 220V is voltage for civilian use (also including most of industry and farming power)；10KV is zonule supply voltage at 6-10 kilometers In the range of power；66KV is larger area supply voltage, the km of its supply district about 80；220KV is used in big region Power supply, in the range from 250 kms, and 550KV power networks are that, across big regional power grid, the distance that it transmits electric power can farthest be arrived More than 800 kilometers.500th, 800 kilovolts of direct current transportation transmission range is farther, and line loss is lower.

For parallel concentration DC boosting type enters web frame, every distributed generator independent connection voltage-source type Transverter (voltage source converter VSC) constitutes a unit therewith as current converter, and distribution is sent out The AC energy that group of motors sends is converted into direct current energy, then unit is connected side by side by direct current, makes the distributed electrical Internal electric network of standing is made up of direct current cables completely, constitutes direct current network structure.Using high power D C converters as straight in structure Mobile substation, mode of operation is boost mode, and its DC voltage for being responsible for merge on dc bus is increased to about 25kV, is led to Cross DC power transmission line and be sent to distal end high-voltage convertor station, complete electrical energy transportation under voltage levels and direct current is grid-connected.

In general, the VSC being connected with bulk power grid possesses the function of energy in bidirectional flow, to realize direct current net and to exchange Electric energy between net is exchanged and power-balance.System is capable of achieving active and reactive power solution lotus root by the control to pusher side VSC. Due to being parallel-connection structure, voltage constant, therefore a DC converter for being operated in boost mode is chosen, the DC voltage that will be converged Raise, then powered to receiving end through long cable transmission.DC converters can be using the simple monocyclic control of strategy, also can be using double Ring, multiple feedback loop.Lower graph structure is fitted with DC stepup transformers, two-stage boost configuration in every distributed motor exit and net side With certain representativeness.Power solution lotus root can be used by pusher side VSC in figure, realize unity power factor control, stabilization rectification Device output voltage, with good temporary steady-state characteristic.

The direct current grid connection topology structure (such as Fig. 2) of this use separate unit DC stepup transformers, it is possible to prevente effectively from circulation occurs；Together When, can be again filtered when boosting is concentrated by the control to DC converters, improve the quality of power supply.

Preferably, also including intelligent energy scheduling control system, the intelligent energy scheduling control system can be realized Distributed power grid supply of electric power.
