In order to implement the central government’s major deployment of preventing and punishing statistical falsification, improving the authenticity of statistical data, and further improving the science and accuracy of power grid project funding forecasts. By studying the fund payment law of power grid infrastructure project and constructing the theoretical capital progress curve model of power grid infrastructure project, the progress and time point of fund payment in each link of the whole process of the project can be effectively controlled. Scientific prediction of the project life cycle at all stages of the fund demand, financing arrangements and payment control to provide a reference.

Direct-drive wave energy converter (DD-WEC) is limited by low power density caused by low direct-drive speed. A tubular hybrid field-modulated linear generator is proposed to improve the performance of DD-WEC. The generator adopted a field-modulated design to increase the output voltage of the linear generator. A hybrid excited field coil can be used to adapt to different wave situations and effectively improve the output performance of this kind of generator. The operation of the proposed generator is analyzed, and the generator performance is evaluated through finite element method and compared with those of three other generators, namely, a field modulated linear generator with parallel magnetic-circuit, a secondary surface PM field modulated linear generator, and a secondary surface PM fractional-slot linear generator. Results show that the proposed generator exhibits high power density and low cogging force. The steady output power and output voltage of are marginally higher in the proposed generator than in the conventional generators.

To solve the low power density disadvantage of direct-drive wave energy converter, caused by low direct-drive speed. A novel linear tubular field modulated permanent magnet generator is proposed, which can effectively improve the performance of this kind of generators. The operation of the proposed generator is analyzed. The generator performance is evaluated using finite element method. The results show that the proposed generator has advantages of larger air-gap effective area, higher power density, more steady output power and voltage, low cogging fore and harmonic component, which is well suit for wave energy conversion.
