The only totally independent electricity in Canada is transmitted a supplier AltaLink and announced, will build the brand-new IP communication network at a high speed, in order to connect Alberta 270 transformer substations inside the province.
AltaLink hopes to realize the treatment to real-time dataflow in the first-phase project of this summer. The chief engineer Clinton Struth of company’s network communications says: “As build the intersection of IP/MPLS and the intersection of network and Utilities Electric Co. of framework by first Canada, AltaLink takes a step innovated, this will help us to manage and transmit the network framework better, will guarantee to realize higher dependability, security and cost advantage. Alcatel Lucent has realized the support to key application through to the design of this network, for example control and gather SCADA with the data With protecting TPR long-rangely Wait, its IP/MPLS solution is playing a key role in the network strategy of future generation that we implement. This strategy is devoted to combining and strengthening the business to hand over, reduce annual capital expenditure and operation and maintenance cost at the same time, support us to realize future growth and network are expanded. ”
The overall IP/MPLS leading solution of Alcatel Lucent will support the intellectual electric wire netting Smart Grid of AltaLink The transition of technology and network of future generation, contribute to the managerial ability of its power system of promotion and efficiency of supply of electric power. Newly-built the whole IP network will support key application and data demand for electricity in AltaLink service area, guarantee AltaLink realizes the lasting gradual progress of the internal data network, in order to offer the supply of electric power by way of economic, high dependability when the customer need. Alcatel Lucent will offer the business router SR for this project Products, include 7750 the intersection of business and router and 7705 business assemble the router, and employ and perceive managing device and 5650CPAM to control the level to ensure the managing device to realize the end is gone to the end to manage in an all-round way through 5620 SAM business. Meanwhile, Alcatel Lucent offers professional service and network maintenance. AltaLink will also dispose Alcatel Lucent VPN Firewall Brick fire wall and 6855 Hardened LAN switch exchanger, dispose the giga Ethernet exchanger designed for IP network specially, is suitable for the environment of operation with very harsh condition.

The ones that strengthen energy efficiency and reduce the gas discharging ” Green ” The car, is strengthening and protecting and improving these two great main trends of safe function level and driving the development of the car of new generation. Obviously, adopting the car designed in green environmental protection is might not be a mixed dynamic automobile HEV . In fact a lot of traditional technology can make the car accord with the requirement for environment protection further, help, improve the intersection of fuel and efficiency and reduce gas, discharge, for example direct fuel spray and variable valve control, park the intersection of jar and economize on fuel, the intersection of turbine and pressurized engine, lubricate engine,etc..
By the look of energy-conserving angle, we saw different design and ” green car ” of the style . Some can let consumers meet their needs with less budgets among them. Start / stop Start-stop The function is the reasonable energy-conserving function of a price. This kind of function makes the internal-combustion engine suspend operation automatically when the car meets the red light or blocks up. OEM of Europe has already regarded this kind of function as their standard function of major platform. Whole of starting / stopping the extra cost that the function involves is only 300 US dollars, but can save 3% to 10% of the fuel, the result is very prominent. If the car goes in the city with very crowded traffic, even can save the fuel up to 25%. Because start / stop the function and run in a standard 12V power network, it is needn’t expensive getting higher for voltage for system, or slightly and mixed dynamic automobiles the whole HEV Necessary extra energy storing battery, this kind of prime cost advantage designed as this function.
Certainly, for a lot of people, HEV equates with the future green car, but we should notice HEV have many it is designed that different in development, include exchanging the engine ISA through the integrating actuator Realizing pure miniature HEV that starts / stops the function, increasing the whole HEV that the pure electricity is driving efficiency and inserting electricity type HEV constantly, various designs are a feast for the eyes. Because need 600V high voltage electronic system between 1,200V slightly and overallly and insert electricity type HEV, this makes the design more challenging. In order to provide enough electronic engine power for car of the electronic engine, or bring sufficient support to the internal-combustion engine, needed some large-scale engines to drive, and these large-scale engines were only applied to industrial world in the past, entering application of car progressively now. In addition, must also reach electronic dynamical system and other new-type electronic system integration in the new HEV car framework.
The new-type electronic system includes realizing DC/DC converter that the energy conveys between 12V and high voltage power network, and air conditioner, motive force turn to numerous electrons such as the system and drive the system. All a challenge for automobile engineering and semi-conductive field, because people were used to working under the environment of 12V battery in the past, but would suddenly face the danger that the high voltage electron brings now, so must isolate these dangerous electronic systems safely.
In addition, will dispose extra peripheral systems and energy and batteries and manage the unit in high voltage framework of HEV. So, we must manage the field to develop reliable, advanced driver IC and switch in the power in order to deal with the challenge of the car environment, its efficiency and cost-effective must be able to guarantee the whole technology of designing concept is pratical and feasible, the price will not exceed users to accept the range at the same time. The power of IR can support the above-mentioned all requirement, but the technology that the main challenge that HEV faces lies in battery while managing the semiconductor.
Even to this day, the battery including lithium ion electricity of new style, all have technological restriction and shortcoming, for example can only walk in the limited distance between holding the electricity twice; Long charging time; And battery high cost, huge volume and weight. In the global battery while manufacturers make great efforts to improve the electrochemical technology of battery, we believe that can manage the solution through the electronic battery of intelligence, promote the battery to improve constantly, in order to lengthen the life-span of the battery, offer and behave more well, and reduce the cost, volume and weight.
Green environmental protection is designed to bring the new challenge of power management to the automobile industry with HEV, international rectifier company IR Have the advantage of being absolute in this respect. IR has experience that long industrial engine drives power management, make us become unique semi-conductive suppliers of car. IR can offer high voltage power switches such as the high voltage driver IC and IGBT,etc.. Today, we have already had a first-class engine to drive the products camp, and plan to introduce and exceed the new car products that 200 fund is especially environment design of abominable car within future 12 months. Control IC as the example with our engine, this IC has already integrated many kinds of safe functions, in order to prevent the calamitous trouble when the electric engine shorts out. In addition, the newest one has no key to shut the thread car and use DirectFET product line, not only bring very low leading the open resistance for the designs of DC/DC converter and battery administrative system, having avoided the key and shut threads even more at the same time, thus can be under very fast switch state, the parasitic inductance can basically be up to zero, there is first-class EMI that behaves at the same time.
The car business segments of IR have five product lines, including high voltage driver IC, intellectual power IC, intellectual switch, MOSFET, and is suitable for the basic, normal, high high voltage IGBT switch up to 1,200V. IR can nearly all power found in a modernized HEV manage application, offer the overall chip group’s solution.
