Description
Technical Field
The invention relates to the technical field of new energy stations, in particular to a phase modulator evaluation method and a phase modulator evaluation device.
Background
The new energy station in the high-proportion new energy collection area has the problems of weak active supporting capacity, low short-circuit ratio of multiple stations, transient overvoltage, low voltage and the like after a power grid fault, and has poor system fault disturbance impact resistance, so that the new energy is severely restricted from being sent out. The relevant requirements of national standards are that "in areas with high proportion of new energy grid-connected power generation, new energy stations should provide necessary inertia and short-circuit capacity support". The phase modulator has instantaneous reactive power support and strong short-time overload capacity, can effectively solve the problem of insufficient short-circuit capacity support of the new energy station, and improves the new energy sending capacity, so that the attention of relevant students and enterprises is widely aroused. With the continuous construction and transportation of new energy stations and the change of the net rack, the output limit of the new energy stations in the same area can be improved, and economic indexes concerned by enterprises preparing to install phase modulators are more diversified, including investment, operation and maintenance, loss, income, recovery time period and the like. Different phase modifier schemes are difficult to intuitively judge which scheme has better economical efficiency by directly comparing indexes. Therefore, a systematic method for evaluating economic indicators more objectively is needed.
Currently, there is less literature on the economics of phase modulators. The traditional economic algorithm adopts standard driving, minimum cost and project-oriented evaluation, and has the advantage of minimum long-term cost, but the investment cannot be reduced, and the budget is reduced. The current technical scheme provides that the economical analysis is carried out on the camera by using a cost-benefit increment ratio (IB/C) method, and the economical analysis is based on the ratio of the gain increment to the cost increment. The current technical scheme also provides that index weights of different evaluation factors are determined according to index scores, and screened indexes comprise unit improvement of new energy output electric quantity, unit capacity investment and equipment operation loss; the two schemes only consider the benefits and the cost in consideration of indexes, do not consider the influence of cost recovery time, and lack the influence of related indexes. The current technical scheme also provides an equal-annual-value method for economic evaluation, and the method is based on the cash flow of the investment scheme and the current value of annual cash flow which is calculated averagely during the utility period. However, the scheme needs to invest the total cash flow of the scheme in the future utility period, and due to the continuous delivery of other new energy stations and the change of net racks, the prospective planning time generally considers the next 5 years, so that the cash inflow of the station in the future utility period is difficult to evaluate and calculate.
